Plastic Diaphragm Valve is a special type of cut-off valve. The biggest difference between the Plastic Diaphragm Valve and other valves is that the structure without stuffing box is adopted; the rubber diaphragm can completely isolate the corrosive medium in the flow passage from all driving parts, thus eliminating the disadvantages of the common valve such as "running, emitting, dripping and leaking".

The features of plastic diaphragm valve as follows
(1) the soft Rubber Diaphragm Valve can cut off the medium.
(2) because rubber has certain corrosion resistance, it is generally used as corrosion-resistant materials to promote application, and continues to today.
(3) the flow path is simple and has the function of "self-cleaning", which can be used for unclean media.
(4) it is suitable for the transportation of corrosive medium, the regulation of closure and flow. The body touch medium use PVC, CPVC, PVDF , PP. It has excellent corrosion resistance, convenient operation, light volume and can replace stainless steel valves.
(5) the seal diaphragm is made of PTFE or PFA, with fold resistance ≥ 1200 times, and corrosion resistance equivalent to F4.
(6) adopt screw lifting structure, with large opening and closing torque and good stability.
