What is PVDF ball valve？
PVDF ball valve is a type of control valve made from polyvinylidene fluoride (PVDF), a thermoplastic polymer commonly used in industrial and chemical processing applications requiring high purity, heat resistance, and chemical resistance. This material makes the PVDF ball valve highly durable and able to withstand extreme temperatures, as well as corrosive or caustic chemicals.
The design of the PVDF ball valve consists of two main components: a cylindrical body with an internal disc that moves along the axis of the valve. When open, the disc blocks off flow between two pipe sections; when closed, it seals off against pressure from either side. The benefit is its ability to completely shut off flow on both sides for tight sealing capabilities without relying on outside sources such as gaskets or O-rings.
What industries are PVDF ball valves used in?
PVDF (polyvinylidene fluoride) ball valves are used in a variety of industries including industrial manufacturing, chemical processing, and water/wastewater treatment. They are one of the most versatile types of valve and can be used to handle even highly corrosive fluids and gases.
In the manufacturing sector, PVDF ball valves are often deployed to control processes such as bleaching or dying operations with acids and caustics. This is because they can resist degradation from potentially harmful chemicals better than other common materials like metal alloys. Furthermore, their lightweight, compact design makes them ideal for quick installation in tight spaces – particularly attractive features for manufacturers that need to stay efficient while dealing with hazardous substances.
In chemical processing plants too, the superior resistance of PVDF allows it to reduce downtime caused by maintenance requirements compared with other types of materials like metals or polymers when exposed to high temperatures or aggressive chemicals; an important consideration for many chemical plants looking to maintain production tolerances while navigating safety protocols.
How to install PVDF plastic ball valve？
Installing PVDF (polyvinylidene fluoride) plastic ball valves is an involved process, however with the right tools and knowledge it can be a straightforward task.
First, identify the location in the system where you want to install the valve and mark it off with a marker or pencil. If needed, cut into pipe to create room for installation. Next, prepare your piping by cleaning it thoroughly on both sides of where you intend to fit the valve in order to reduce any contaminants that might cause corrosion or impede proper sealing of the fitting using water and breathing mask/respirator for safety purposes.
Thirdly, determine which type of adhesive will suit your needs – there are many types available for PVDF plastic ball valves such as cyanoacrylate-, epoxy- and UV-curing adhesives – before applying sufficient amount per instructions on manufacturer’s product specification label inside adhesive container. Fourthly, carefully position your PVDF plastic ball valve into place after making sure that O-ring gasket is set correctly inside seat area and that valve handle is aligned parallel using spanners or vice grips if necessary; tighten screws while ensuring seal remains tight without leaking fluids out during operation stage.
Finally connect required tubing connections by attaching next sections onto each side of newly installed plastic ball valve then inspect entire installation one last time before allowing system back up again for testing procedure stages; make certain all components have been secured properly!
Can PVDF ball valves prevent corrosion?
Yes, PVDF ball valves are specifically designed to resist corrosion. Polyvinylidene fluoride (PVDF) is a thermoplastic polymer that has superior chemical resistance due to its high-polarity and inertness. It can even withstand highly corrosive industrial chemicals as well as hot, boiling fluids like those present in steam service conditions.
PVDF ball valves are also used as check valves since the material’s self-lubricating properties reduce the chances of a valve stuck in the closed position by corrosion deposits or crystallization of salts on internal surfaces and threads. This makes PVDF ball valves ideal for applications involving fluids with extremely low lubrication including water, ethylene glycol, sea water, mineral oil and other aggressive solvents like hydrofluoric acid (HF), nitric acid (HNO3), phosphoric acid (H3PO4), sulfuric acid (H2SO4) and acetic anhydride as well as halogenated agents suchas carbon tetrachloride(CCl4).
