How is an electric actuator valve different from a manual one?
Introduction
Valves are essential components in many industrial processes and applications. They serve the function of controlling fluid or gas flow. Two main types of valves exist: electric actuator valves and manual valves. Manual valves have been in use for centuries. Electric actuator valves are modern inventions that revolutionized the industry. Understanding the difference between these valves is essential for those interested in valves. This article is a guide on the differences between electric actuator and manual valves. It covers their pros, cons, ideal applications, how they work, and advantages. It also highlights various applications where these valves excel.
What is an Electric Actuator Valve?
Definition and explanation of electric actuator valves
Electric actuator valves are a type of valve that uses electrical energy to operate its actuator, which in turn opens or closes the valve. The electric motor is the primary component of an electric actuator valve, which converts electrical energy into mechanical energy. Electricity flows through the electric motor of the electric actuator valve. This causes the valve to open or close by rotating gears and cams in the actuator. These valves can be controlled remotely or set up to work automatically. They are ideal for various industrial applications requiring precision control. Electric actuator valves are faster and more precise than manual valves. This makes them a preferred choice in many modern applications.
How it works
The working principle behind electric butterfly valve is relatively simple. When an electric current passes through the actuator, the electric motor receives the signal to rotate, causing the valve to open or close. Electric actuator valves come in two different types – on/off valves and control valves. On/off electric actuator valves control fluid or gas flow in open or closed states. Control valves enable variable control over the fluid or gas passing through the valve. To operate a control valve, the electric actuator receives a varying electric current signal. The signal controls the valve’s position to maintain specific flow rates. Electric actuators can integrate with other control systems for more comprehensive control. This can include control over fluid or gas flow, temperature, and pressure.
Advantages of using an electric actuator valve
Electric actuator valves offer several advantages that make them the preferred choice in many applications. First and foremost, electric actuator valves offer precise control over fluid or gas flow, making them ideal for use in applications that require high levels of accuracy, such as laboratory experiments, water treatment plants, and chemical processing facilities. Additionally, electric actuator valves can be operated remotely, reducing the need for manual intervention and increasing safety. They are also faster to operate than manual valves, improving process efficiency and reducing labor requirements. Electric actuator valves are also more consistent than manual valves, eliminating the variability that can occur with hand-operated valves. Finally, they are low maintenance and have a long lifespan, reducing maintenance costs and keeping production downtime to a minimum.
III. What is a Manual Valve?
Definition and explanation of manual valves
Manual valves operate by hand or mechanical lever, gear, or actuator. Industries have used them for centuries due to their simple and reliable nature. They control fluid or gas flow by manually turning a handle or lever to open or close the valve. They come in many different types, including gate valves, ball valves, and butterfly valves, each with unique features and advantages. Manual valves are widely used in low-pressure applications or facilities where automation is not necessary or feasible. They are also relatively inexpensive and easy to maintain, making them a popular choice in many applications. However, manual valves can be slow to operate, require manual adjustment and carry a higher risk of human error compared to electric actuator valves where the operation can be easily automated.
How it works electric valve
To open or close manual valves, operators turn a handle or lever manually. Rotating the handle or lever blocks or allows flow through the valve by moving a ball, disc, gate, or plug inside the valve body. When open, fluid or gas flows through the valve body, and when closed, it is blocked. The valve’s open or closed position depends entirely on the position of the handle or lever, with a ball valve, for example, rotating 90 degrees to either block or open the flow path completely. Manual valves require no external power source to operate, making them dependable and simple to use. However, manual valves offer less precise control over fluid or gas flow than electric actuator valves and require manual adjustment, which can be time-consuming and prone to human error in some cases.
Advantages of using a manual valve
Manual valves have been in use for centuries, and they continue to offer several advantages that make them a popular choice in many applications. First and foremost, manual valves are easy to use and require no external power source to operate, making them ideal for remote locations without access to electricity. They are also relatively inexpensive and easy to maintain, which can significantly reduce maintenance costs. Additionally, manual valves can handle high-pressure and high-temperature applications, making them ideal for use in extreme environments. They are also highly adaptable, with a wide range of sizes and materials available to suit the needs of almost any application. Manual valves offer reliable and straightforward operation, allowing them to be used in most applications where high precision is not critical, and automation is not necessary.
Differences Between Electric Actuator and Manual Valves
Performance differences
One significant difference between electric actuator and manual valves is their performance. Electric actuator valves offer faster and more precise control than manual valves, as they can be automated and remotely controlled, reducing the risk of human error. Additionally, electric actuator valves can be programmed to change flow rates in real-time, making them ideal for use in applications that require extremely precise control. Manual valves, on the other hand, offer slower and less precise control than electric actuator valves, as they rely entirely on the operator’s skill to adjust them accurately. Although manual valves are simple and reliable, their performance is limited to the operator’s ability to adjust them manually. Therefore, electric actuator valves are often preferred in applications requiring high precision and optimal control over fluid or gas flow.
Cost differences
Maintenance differences electric valve
Another significant difference between electric actuator and manual valves is their maintenance requirements. Electric actuator valves require more maintenance than manual valves, primarily because they are more complex and contain more moving parts, such as the electric motor and gears or cams in the actuator. Regular maintenance is essential to ensure that electric actuator valves continue to operate optimally and reliably. In contrast, manual valves have fewer moving parts and are easier to inspect, maintain and replace. They require less maintenance, and when correctly installed and operated, they can offer reliable operation for extended periods. Therefore, manual valves are generally preferred in applications where maintenance requirements need to be kept minimal.
Customization differences
Finally, another difference between electric actuator and manual valves is their level of customization. Electric actuator valves are highly customizable, and they can be integrated with other valve components, such as position sensors or pressure regulators, to offer more comprehensive control over fluid or gas flow. They can also be programmed to switch flow paths quickly, making them ideal for use in diverse industrial applications. On the other hand, manual valves offer fewer customization options than electric actuator valves. They have a more straightforward design, and they are limited to the operator’s ability to control fluid flow manually. However, manual valves can be customized to specific sizes, shapes, and materials to suit specific applications, making them ideal for use in bespoke or custom applications. Therefore, the choice between electric actuator and manual valves depends on each application’s level of complexity, customization requirements, and precision control requirements.
