What Is a PVDF Diaphragm Valve?

PVDF diaphragm valve is a pressure relief valve for control of the flow of fluids in various industrial piping systems. The PVDF valve is made up of the polyvinylidene fluoride, which is one of the thermoplastic materials. This material has excellent chemical and electrical properties. It has high resistance to acids, chlorinated solvents, salts, and dilute bases. It is also abrasion resistant. Hence, it is suitable for a wide variety of applications.

The PVDF diaphragm valve has the ability to withstand a wide range of pressures and temperatures. It is ideal for controlling the flow of various liquids and minerals in different industries. It is particularly used in the pharmaceutical industry. The PVDF diaphragm valve is available with a hand wheel for easy opening and closing of the valve.

The PVDF diaphragm can be actuated by pneumatic, electric, and hydraulic means. However, the actuation method depends on the size and specifications of the system. The PVDF diaphragm is suitable for both on/off and pressure relief applications.

The PVDF diaphragm is also available with a gas barrier layer to prevent the permeation of chlorine or chlorinated gases. This material is also resistant to abrasion and salts. It has a design stress of 1,360 psi at 73degF. Nevertheless, this material is susceptible to damage in corrosive environments. In such environments, the laminated PTFE layer can become delaminated. Therefore, it is important to choose a durable material that will not deteriorate when exposed to a highly corrosive environment.

PVDF diaphragm valves are designed for use with a variety of fluids, including hydrochloric acid, organic acids, and acetic acid. They are also suitable for high-purity applications that require high purity and high strength. In order to determine the right valve type, you should first know the maximum pressure and volume of the fluid you are handling. Then, you need to calculate the forces that are required to block the flow. Once you have determined the correct size, you can proceed to determining the actuation mechanism.

There are many PVDF diaphragm valves to choose from. You can select from pressure relief, low-pressure, and actuated models. The diaphragm valve is designed to shut off up to 10 bar operating pressure. The valve can be made with a metal or plastic body, and it can be fitted with flanges or welded connections. These valves are often used in high-purity liquid transportation applications. They are also used in food and beverage industries.

For tough applications, it is best to use the Diaphragm Valve Type 14. This valve is made from solid thermoplastic materials, which is designed to provide bubble-tight sealing. It also has a one-piece moulded construction. This prevents the development of production joints and eliminates compressive strain. It also features a built-in travel stop, which prevents overtightening of the diaphragm. This type of valve also has a visual position indicator to show the valve's position. The color indicator will go out of view when the valve is fully closed.
