PVC Diaphragm Valves

PVC diaphragm valves are usually used for slightly more complex commercial or industrial applications. They use a membrane or "diaphragm" to restrict or allow flow. The valves we supply on PVC Fittings Online are manual, but diaphragm valves can also be automated (actuated). Our valves are made with a durable PVC body, allowing the valve to stand up to harsh industrial conditions. Diaphragm valves can come in a range of body and seal materials. Our valves are PVC with EPDM seal material.

Diaphragm valves were originally created to fill a need in industrial applications, but have since become more widely used. There are various types of diaphragm valve. Our valves are the most common design, a two-way shutoff valve. PVC makes for an ideal valve material in many applications due to its ability to resist corrosion and withstand a number of common chemicals.

Our selection of PVC Diaphragm valves feature socket ends. These valve ends are made to accept PVC pipe of the same size, forming a liquid-tight bond with the use of solvent cement during installation. Our valves are manual style, meaning they require an operator turning the wheel to open and close the valve.

Available in a range of sizes, our PVC diaphragm valves start at 1/2 inch size and go up to 2 inch. We carry two quality brands for you to choose from. Both employ EPDM sealing material, which is resistant to a long list of common chemicals and provide a tight seal so liquid media cannot pass.
