Threaded stainless steel ball valves offer faster and easier installation than flanged types. The design of a threaded ball valve requires fewer steps and less equipment. The installation process for threaded stainless steel ball valves is more straightforward compared to flanged types, making them a preferred choice for many applications. Workers often prefer this valve for standard piping because it saves time and reduces errors. Stainless steel ball valves provide a quick on/off flow control operated by a quarter-turn of the valve handle. In contrast, a flanged valve demands more alignment and tightening. Stainless steel ball valve options also include pinch valve and butterfly valve types, but many industries choose ball valves for their reliability in piping systems.
Flanged vs Threaded: Key Differences
Connection Types
Valve connections play a crucial role in the performance and reliability of any piping system. Flanged connections use bolted circular discs and gaskets to create a strong, fluid-tight seal. These connections handle high pressure, temperature, and chemical exposure. Flanged connections are reusable and allow for easier assembly and disassembly, especially in large-diameter piping. Threaded connections, on the other hand, rely on screw threads to join the valve to the pipe. These connections are compact and lightweight, making them ideal for tight spaces and smaller valves.
Threaded connections are easy to install and maintain, but they may not provide the same level of strength as flanged connections in demanding environments. Stainless steel ball valves are manufactured in high grade 316 stainless steel, although some variations in SS 304 are offered. The two-piece ball valve is probably the most widely used ball valve. Stainless steel ball valves are available with a variety of end connections, including threaded and flanged types. Apollo offers a 1 inch 2 Piece Full Port Stainless Steel Ball Valve, which is a popular choice for many applications.
| Performance Metric | Threaded Connections | Flanged Connections |
|---|---|---|
| Pressure Rating | Suitable for smaller valves (under 4 inches); limited for larger sizes due to sealing difficulties | Suitable for high-pressure and severe conditions |
| Leakage Prevention | Tight seal but prone to leakage in larger sizes; requires pipe tape or sealant for extra sealing | Provides a secure, robust, and reusable seal |
| Ease of Installation | Easy to install, maintain, and replace; inexpensive | Requires skilled labor; more complex installation |
| Cost | Cost-effective, especially for smaller valves | More expensive, especially specialty flanges |
| Size and Weight | Compact and lightweight | Bulkier and heavier |
| Suitability | Ideal for smaller diameter valves and less severe conditions | Suitable for large valves and harsh operating environments |
Pressure and Temperature Limits
The choice between flanged vs threaded valve connections often depends on the pressure and temperature requirements of the system. Flanged connections excel in high-pressure systems and can withstand thousands of PSI and temperatures above 1000°F. This makes flanged valves the preferred option for chemical processing, power generation, and other demanding industries. Threaded connections work best in low to medium pressure and temperature settings. These connections may struggle to maintain a reliable seal under extreme conditions, especially in larger sizes. Flanged valves often use metal or composite seals, which provide better performance in harsh environments. Threaded valves typically use soft seals like PTFE, which may not hold up as well under high pressure or temperature.
Application Suitability
Selecting the right valve connections depends on the specific needs of the application. Flanged vs threaded options each have their strengths:
- Flanged valves suit high-pressure, high-temperature, and corrosive environments. Industries such as petrochemicals, shipbuilding, and metallurgy rely on flanged connections for their durability and robust sealing. Flanged valves also allow for easier maintenance, as workers can replace gaskets and perform repairs without disturbing the entire piping system.
- Threaded valves offer a cost-effective solution for residential water supply, small industrial equipment, and light process control. These valves are easy to install in confined spaces and require minimal tools. However, threaded connections may loosen over time due to vibration or thermal changes, which can lead to leaks.
- Flanged valves, despite higher initial costs, often prove more economical in the long run for rigorous applications. Their blowout-proof design and strong valve connections reduce the risk of failure and lower maintenance needs.
- Industries that commonly use stainless steel ball valves include chemical, agricultural, construction, pharmaceutical, and food and beverage industries. Some stainless steel ball valves are equipped with an ISO 5211 mounting pad to facilitate actuator installation for automated control. Pro Flow Dynamics supplies quality stainless ball valves at wholesale prices and has customers throughout the United States, Mexico, and Canada.
SS Ball Valve Installation Steps
Proper installation of a stainless steel ball valve ensures a fluid-tight seal and long-term reliability. The process differs for threaded and flanged connections. For best results, always follow the manufacturer’s installation instructions to ensure proper sealing and reliable operation. Each method requires attention to detail, correct alignment, and the right sealing techniques to achieve a secure assembly. The ball valve operates by turning the valve handle 90 degrees which rotates the ball to either open or close the flow.
Threaded Ball Valves
Preparation
- Turn off the fluid supply and depressurize the system. This step prevents accidents and ensures safety during installation.
- Inspect the valve standard port, seating surfaces, and threads. Remove any dirt, debris, or old sealant from the connections. Make sure to completely remove any old pipe dope or PTFE tape before applying new sealant.
- Operate the valve from fully open to fully closed. This check confirms the valve functions correctly before installation.
- Clean and dry the pipe ends. Accurate threading and cleanliness help prevent leaks and cross-threading.
Tip: Always verify that the threaded connections match the valve connections for size and thread type. This step avoids misalignment and ensures a proper fit.
Sealing Threads
- Apply PTFE (Teflon) tape or an approved pipe thread sealant evenly around the male threads. Cover the threads without overlapping into the valve body.
- Follow the manufacturer’s instructions for the sealing material. Proper sealing prevents leaks and supports a fluid-tight seal.
Tightening
- Align the valve and piping carefully. Hand-tighten the valve onto the pipe to avoid cross-threading.
- Use two wrenches when tightening two-piece body threaded ball valves. Hold the valve body steady with one wrench and tighten the connection with the other. This method prevents stress on the valve body and maintains alignment.
- Tighten the joint until the valve points in the desired direction. Do not overtighten, as this can damage the threads or the valve.
- Support the piping to maintain alignment and avoid undue stress on the valve connections.
- Turn the fluid supply back on slowly. Check for leaks at the threaded connections. If leaks appear, tighten slightly or reseal as needed. Resellers can call for special pricing for bulk orders.
Tip: Installing a union fitting near the threaded valve allows for easier future maintenance or replacement.
Note: Proper alignment and torque are critical. Never back off a threaded connection to reposition the valve, as this can compromise the seal.
Flanged Ball Valves
Preparation
- Turn off and drain the system to depressurize it. Safety comes first in every installation.
- Gather all necessary materials, including the flanged ball valve, gaskets, bolts, and tools. Note: Stud bolts are commonly used for securing flanged connections.
- Clean and inspect the flange faces and pipe ends. Remove rust, dirt, or debris to ensure a smooth surface for the gasket and flanged connections.
- Check the gasket condition. Use the correct gasket type for the pressure and temperature requirements of the system.
Gasket Placement
- Position the gasket between the flanged faces. Make sure the gasket sits evenly and covers the sealing surface completely. For high-pressure or high-temperature flanged connections, a spiral wound gasket is often recommended.
- Align the flanged valve between the pipe flanges. Ensure the bolt holes match and the valve handle remains accessible for operation.
Tip: Proper gasket placement is essential for a fluid-tight seal. Misaligned gaskets can cause leaks and reduce the effectiveness of the flanged connections.
Bolting and Alignment
- Insert bolts through the aligned flanged connections. Hand-tighten the bolts to hold the valve in place.
- Tighten the bolts in a crisscross pattern using a wrench or torque wrench. Follow the manufacturer’s recommended torque values to ensure even pressure across the flanged connections. The correct torque value is critical to prevent leaks and ensure proper sealing.
- Check the alignment of the valve and piping. The valve should sit squarely between the flanges, with no visible gaps.
- Perform a final inspection. Confirm that all bolts are evenly tightened and the valve operates smoothly.
- Slowly restore the fluid supply. Monitor the flanged connections for leaks and verify the valve’s performance.
Note: Always use the correct torque and tightening sequence. Uneven tightening can lead to leaks or damage to the flanged connections.
A successful installation of a stainless steel ball valve depends on careful preparation, correct sealing, and precise alignment. Following these steps reduces the risk of leaks, supports a secure assembly, and extends the life of the valve connections. Quantitative risk models in industrial settings show that best practices and safety tips during installation lower the likelihood and severity of failures, reduce product loss, and minimize maintenance costs. Operators who follow these guidelines achieve a reliable, fluid-tight seal and maintain system integrity.
Tools and Time for Installation
Threaded Valve Tools
A threaded valve requires only a few basic tools for installation. Most installers use two adjustable wrenches to grip the valve body and the pipe. PTFE tape or pipe thread sealant helps create a leak-free seal on the threaded connections. Some workers keep a wire brush handy to clean the threads before assembly. These tools fit easily in a small toolbox and do not need special training to use. The compact design of threaded valve connections allows for quick work, even in tight spaces. Installers often finish the job with a simple leak check using soapy water. After installation, the handle should be checked for smooth operation to ensure proper function. Valworx 551808A stainless steel 2-piece ball valves are designed for use with water, air, oil, and other media compatible with the materials of construction. TCI usually ships their ball valves in 24 hours, ensuring quick availability for urgent projects.
Common tools for threaded valve installation:
- Adjustable wrenches (2)
- PTFE tape or pipe thread sealant
- Wire brush
- Soapy water for leak testing
Tip: Always use two wrenches to avoid twisting the valve body and damaging the threaded connections.
Flanged Valve Tools
A flanged valve installation needs more equipment and careful handling. Workers use torque wrenches to tighten bolts to the correct value. They also need a set of bolts, nuts, and washers that match the flanged connections. Studs are another common component used to secure flanged valves, providing a reliable method for joining flanges. Gasket alignment tools help position the gasket between the flanged faces. For larger valves, lifting equipment or supports may be necessary because flanged valves are heavier and bulkier. The installer must check the alignment of the valve connections before tightening the bolts. This step prevents leaks and ensures a secure fit.
Essential tools for flanged valve installation:
- Torque wrench
- Set of bolts, nuts, and washers
- Studs
- Gasket alignment tool
- Lifting equipment (for large valves)
- Cleaning cloths for flange faces
Note: Proper torque and even tightening are critical for flanged connections. Uneven pressure can cause leaks or damage the valve.
Time Comparison
Threaded valve installation usually takes less time than flanged valve installation. Most installers can complete a threaded valve job in under an hour, even with careful cleaning and leak testing. The simple design of threaded connections means fewer steps and less chance for error. Flanged valve installation takes longer because of the extra steps. Workers must align the flanged connections, place the gasket, insert bolts, and tighten them in a specific pattern. Large flanged valves may require two or more people and lifting equipment, which adds to the time. In most cases, flanged valve installation can take several hours, especially for large-diameter valve connections. This extended installation time can increase system downtime.
| Installation Step | Threaded Valve (Time Estimate) | Flanged Valve (Time Estimate) |
|---|---|---|
| Preparation | 10 minutes | 20 minutes |
| Sealing/Alignment | 5 minutes | 20 minutes |
| Tightening | 10 minutes | 30 minutes |
| Leak Testing/Inspection | 5 minutes | 15 minutes |
| Total Time | 30 minutes | 1.5-2 hours |
Installers should always plan extra time for flanged valve connections, especially in complex systems or when working with large valves.
Common Installation Issues
Threaded Valve Problems
Leaks
Leaks often occur at the threaded connections when installers do not apply enough sealant or use the wrong type. A documented case showed a water valve detaching from a 2.5-inch pipe due to failure in the threaded section. This incident caused flooding and major property damage. Leaks can also result from worn seals, corrosion, or debris inside the valve. Regular inspections help spot leaks early. Technicians should check for moisture around the stem, body, and handle. Tightening fittings or replacing seals usually solves minor leaks. If the valve continues to leak, replacement may be necessary.
Cross-Threading
Cross-threading happens when installers force the valve onto misaligned threads. This mistake damages the threads and weakens the seal. Cross-threading is a common problem during installation and maintenance of threaded valves. It can cause leaks and make future repairs harder. Quick repair techniques exist, but prevention works best. Installers should always align the valve and pipe carefully before tightening. Using two wrenches helps keep the valve body steady and reduces the risk of cross-threading.
Overtightening
Overtightening the valve can strip threads or crack the valve body. This problem often leads to leaks or even valve failure. Installers sometimes overtighten connections, thinking it will prevent leaks. In reality, proper torque is more important than brute force. Workers should stop tightening once the valve feels snug and the handle points in the right direction. Supporting the piping during installation also helps avoid stress on the connections.
Tip: Always follow the manufacturer’s torque recommendations for threaded valve installation. This practice prevents damage and extends valve life.
Flanged Valve Problems
Gasket Leaks
Gasket leaks remain one of the most common issues with flanged connections. Studies show that improper installation, flange damage, and gasket problems account for nearly 70% of flange joint leaks. Gasket leaks often result from using the wrong material, incorrect size, or reusing old gaskets. Environmental factors like temperature swings and corrosive fluids can also degrade gaskets. Installers should always select gaskets that match the process fluid and operating conditions. Regular inspections help catch leaks before they cause major problems.
Misalignment
Misalignment during installation can cause leaks, uneven gasket compression, and even valve failure. Research shows that misaligned flanged connections account for a significant number of installation failures. Using alignment tools helps ensure the valve sits squarely between the flanges. Installers should check that bolt holes line up and that the valve handle remains accessible. Proper alignment protects the gasket and keeps the system leak-free.
Bolt Torque
Incorrect bolt torque is another frequent cause of leaks in flanged connections. If bolts are too loose, the gasket will not seal properly. If bolts are too tight, the gasket or flange can become damaged. Studies recommend tightening bolts in a crisscross pattern and using a torque wrench to apply even pressure. Lubricating bolts and using hardened washers also improve load distribution. Following these steps helps prevent leaks and extends the life of the valve assembly.
Note: Regular maintenance, proper installation, and routine inspections reduce the risk of leaks, corrosion, and other failures in both threaded and flanged connections.
Maintenance and Replacement
Threaded Ball Valves
Threaded stainless steel ball valves require regular care to ensure reliable operation and long service life. Most facilities schedule inspections at least twice per year or every 7.5 months, following safety regulations. During these checks, technicians look for signs of wear, corrosion, leaks, and damage on the stem seals, seating surfaces, and threads. They also clean the valve exterior and flush the interior to remove debris.
A typical threaded ball valve lasts about 8 to 10 years, but this depends on the type of media, temperature, pressure, and how often the valve cycles. Abrasive fluids or suspended particles can wear out seals faster, leading to leaks or failure. Stainless steel valves offer better durability and corrosion resistance than plastic types, making them a preferred choice for demanding environments.
To extend service life, technicians follow these steps:
- Inspect for leaks, misalignment, or worn parts. Be sure to specifically inspect the seat for signs of wear or damage.
- Clean and lubricate threads and moving parts.
- Replace seals, seats, or balls during scheduled shutdowns.
- Store spare valves in dry, ventilated areas.
Three-piece valve designs make maintenance or replacement easier. Workers can swap out seals or seats without removing the entire valve from the pipeline, which reduces downtime and costs. Pressure testing after maintenance helps verify that the valve maintains a tight seal.
Tip: Using filtration systems to keep debris out of the valve can prevent premature wear and lower the risk of failure.
Flanged 2 Piece Ball Valves
Flanged stainless steel ball valves serve in high-pressure and high-temperature systems, so they must meet strict industry standards for maintenance. Organizations like the American Petroleum Institute (API) set protocols for inspection, repair, and quality control. For example, API 6D requires pressure testing at 1.5 times the valve’s rated pressure to confirm integrity. API 598 outlines leakage classifications, while API Q1 covers quality management and traceability.
| Standard | Focus Area | Maintenance Protocol Highlights |
|---|---|---|
| API 6D | Design & Testing | Pressure testing, fire safety, welded bodies |
| API 598 | Pressure Testing | Shell strength, leakage classification |
| API Q1 | Quality Management | Design verification, process control, traceability |
| API 6DR | Valve Repair | Welding repair, defect detection, life assessment |
| API 589 | Fire Damage Assessment | Metallographic analysis, hardness testing |
Routine maintenance for flanged valves includes:
- Inspecting flange faces, bolts, and gaskets for damage or misalignment.
- Cleaning gasket surfaces and replacing gaskets as needed.
- Tightening bolts to the correct torque using a crisscross pattern.
- Performing pressure tests to check for leaks.
- Following manufacturer and API guidelines for repairs and documentation.
Flanged valves often use three-piece designs, which allow for component replacement without removing the valve from the line. This feature minimizes downtime and supports efficient maintenance in critical applications. Two-piece and three-piece valves are full-port, which means the valves’ internal opening is the same size as the pipe it is connected to. One-piece valves are usually reduced-port, which means the internal opening is smaller than the diameter of the pipe.
Note: Proper lubrication, cleaning, and adherence to manufacturer specifications help maintain valve performance and extend service life, especially in harsh industrial environments.
Choosing the Right Valve
Space and Accessibility
Engineers often face space limitations when installing valves. Threaded stainless steel ball valves offer a compact design. These valves fit easily into tight spaces, such as small utility rooms or crowded industrial skids. Workers can install or replace threaded valves with basic hand tools, even when access is limited. Some stainless steel ball valves also feature a mounting pad, which makes it easier to install actuators in confined areas. Flanged ball valves require more clearance for bolt tightening and gasket placement. Large flanged valves may need lifting equipment and extra workspace. In facilities with restricted access, threaded valves provide a practical solution. For large-diameter pipelines or systems with frequent maintenance, flanged valves allow easier disassembly and reassembly.
Tip: Always measure the available space before selecting a valve type. Consider future maintenance needs and the tools required for installation.
Pressure and Temperature Needs
Selecting the right valve depends on the system’s pressure and temperature requirements. Threaded ball valves perform well in low to medium pressure and temperature settings. Flanged ball valves handle higher pressures and temperatures, making them suitable for demanding industrial environments. In one paper mill, a sudden valve closure caused water hammer, sending pressure waves through the system. The surge exceeded design limits and damaged pumps, pipes, and valves. This case shows the importance of choosing valves that can withstand unexpected pressure spikes.
Temperature also affects valve performance. For example, a PN16 valve rated for 16 bar at 20°C may only handle about 11.2 bar at 100°C. Stainless steel maintains its strength at higher temperatures, while cast iron loses capacity. Engineers must consider both the maximum allowable working pressure (MAWP) and the temperature derating of each valve. Stainless steel ball valves are available in different pressure class ratings to suit a range of applications. Using slow-closing valves or surge protection devices can help prevent damage from pressure surges.
| Factor | Threaded Valve | Flanged Valve |
|---|---|---|
| Pressure Rating | Low to Medium | Medium to High |
| Temperature Resistance | Moderate | High |
| Surge Protection | Limited | Enhanced |
| Suitable Applications | Residential, Light Industrial | Heavy Industrial, Critical Systems |
Cost and System Compatibility
Cost and compatibility play a major role in valve selection. Stainless steel ball valves continue to grow in popularity due to their reliability and low maintenance. Industries such as oil and gas, chemical processing, and water treatment value durability and corrosion resistance. Price sensitivity remains high, with many buyers watching raw material costs and supply chain issues. Some companies pay more for smart features, such as IoT-enabled monitoring or predictive maintenance, while others focus on basic functionality.
Valve compatibility depends on size, pressure rating, connection type, and operation mode. Manufacturers segment valves by these factors to match specific industrial needs. Some stainless steel ball valves are available with a welded body construction for applications requiring maximum strength and leak resistance. Regional differences also affect choices. For example, Asia-Pacific leads in industrial valve use due to rapid growth, while North America and Europe emphasize quality standards and automation. Fluctuating stainless steel prices and technical challenges in valve design can impact both cost and procurement strategies.
- Ball valves suit a wide range of industries, from food and beverage to power generation.
- Stainless steel alloys offer strong performance, but costs can vary by region and market conditions.
- Automation and smart valve technologies influence long-term value and compatibility with modern systems.
Note: Always balance initial cost with long-term reliability and system integration. Choose a valve that meets both current and future operational needs.
Installation Best Practices
Safety Tips
Safety remains the top priority during stainless steel ball valve installation. Workers should always wear personal protective equipment, such as gloves, safety glasses, and steel-toed boots. Before starting, they must shut off the fluid supply and depressurize the system. This step prevents accidental release of hazardous fluids or gases. Field research and best practice manuals recommend using stainless steel tubing and fittings to prevent corrosion and scaling, which supports reliable operation. Standardizing installation practices helps reduce errors and improves safety. Many experts suggest using double block-and-bleed valves for added protection during maintenance. Pre-insulated tubing bundles, installed according to manufacturer instructions, help prevent freeze damage in cold environments. Training from reputable sources, like Swagelok’s installation guides, gives workers the skills needed for safe and effective valve installation.
Tip: Always follow manufacturer guidelines and seek advice from experienced field engineers when working with new systems.
Leak Prevention
Achieving a fluid-tight seal is essential for system reliability. Installers should match valve and pipe connections carefully and avoid misalignment. Using the correct torque on bolts and fittings helps prevent leaks. Industry experience shows that two-ferrule, mechanical-grip tube fittings work better than traditional threaded fittings, especially in systems exposed to vibration or temperature changes. While technical studies on leak prevention remain limited, practical hydrostatic testing provides valuable feedback. For example, tests on 4-inch stainless steel floating ball valves show that material selection and valve design play a big role in leak prevention. Choosing corrosion-resistant materials, such as Ferralium 255, can improve performance in harsh environments. Installers should always perform post-installation leak checks, using soapy water or hydrostatic tests, to confirm a leak-tight seal before returning the system to service.
Note: Leak prevention relies on careful installation, proper material selection, and regular testing rather than formal technical studies.
Inspection
Routine inspection ensures long-term valve performance and safety. Industry standards recommend a series of quality assurance procedures and checklists:
- Conduct pressure tests to verify the valve can withstand operational and rated pressures.
- Perform seat tests to check for tight sealing and acceptable leakage rates.
- Carry out shell (body) tests to assess structural integrity. For critical or regulated applications, ‘witness testing’ by a third party may be required to verify valve performance.
- Use advanced inspection techniques, such as non-destructive testing and acoustic emission monitoring, for critical applications.
- Inspect visually for surface defects, coating quality, and welding issues.
- Verify valve dimensions and documentation, including material certificates.
- Schedule regular inspections to detect early signs of wear, corrosion, or damage.
Comparative research benchmarks highlight the importance of proper alignment, correct torque, and material selection for reliable operation. Following these best practices helps maintain a leak-tight seal and extends the service life of stainless steel ball valves in demanding industrial environments.
Threaded stainless steel ball valves install quickly and work well for low-pressure, simple systems. Flanged valves suit high-pressure or high-temperature applications and offer easier maintenance. Users should match valve type to system needs by checking pipe size, pressure, temperature, and maintenance plans.
Quick Valve Selection Checklist:

The 2-piece ball valve is the most widely used configuration, featuring a simple construction that allows for straightforward installation and maintenance. This design typically provides a full port, ensuring maximum flow through the valve and minimizing pressure drop.
For applications where frequent cleaning or servicing is necessary, a 3-piece ball valve offers added convenience. The main body of a 3-piece valve can be easily removed without disturbing the pipe connections, making it ideal for systems that require regular maintenance or where downtime must be minimized. Additionally, the configuration of the valve affects the stem and bore design. Some ball valves are equipped with a triple stem seal, enhancing reliability and reducing the risk of leaks. The choice between 2-piece and 3-piece configurations, as well as considerations like full port or standard port, should be based on the specific needs of your system, including maintenance frequency, flow requirements, and installation space.
Full Port Design
A full port design is a defining feature of many high-quality ball valves, offering significant advantages in terms of flow capacity and system efficiency. In a full port ball valve, the bore—the internal opening through the ball—matches the diameter of the connected pipe. This alignment allows for unrestricted flow, minimizing pressure drop and reducing the risk of clogging or blockages, even when handling viscous or particulate-laden fluids.
Full port ball valves are especially valuable in industries where maintaining high flow rates is critical, such as chemical processing, oil and gas production, and water treatment. The larger bore size not only supports efficient fluid movement but also simplifies cleaning and maintenance, as the unobstructed port allows for easier access and flushing. When selecting a ball valve, choosing a full port design ensures that your system operates at maximum efficiency, with minimal resistance and optimal performance.
Valve Size and Installation
Selecting the correct valve size is essential for ensuring optimal performance and longevity of your ball valve. The valve size must correspond precisely to the pipe size to maintain proper flow rates and pressure ratings throughout the system. Undersized or oversized valves can lead to issues such as reduced flow, increased pressure drop, or even system failure.
Installation is another critical factor in the successful operation of ball valves. Whether you choose a threaded or flanged connection, it’s important to follow manufacturer guidelines for alignment, sealing, and securing the valve. Threaded ball valves are often favored for their ease of installation, especially in smaller sizes, while flanged ball valves provide robust connections for larger or high-pressure systems. Proper installation techniques help prevent leaks, corrosion, and mechanical stress, ensuring that your ball valves deliver reliable performance over time.
