Plastic Diaphragm Valve
Introduction:
A plastic diaphragm valve is a special form of shut-off valve. The biggest difference between the plastic diaphragm valve and other valves is that it adopts the structure without stuffing box;The rubber diaphragm can completely isolate the corrosive medium in the flow channel from all the driving parts, thus eliminating the disadvantages of “running, running, dripping and leaking” of ordinary valves.
Characteristics and Working Principle:
(1) The soft rubber diaphragm valve can cut off the medium.
(2) Because rubber has a certain corrosion resistance, it is usually used as a corrosion-resistant material to promote and apply, and it continues to this day.
(3) The flow path is simple and has a “self-cleaning” effect, which can be used for unclean media.
(4) It is suitable for the transportation of corrosive media and the regulation of flow closure and flow. The flow parts are assembled with RPP or PVDF injection molding parts, which have excellent corrosion resistance, easy operation and light weight, and can replace stainless steel valves.
(5) The diaphragm of the seal is made of F46 or PFA, the number of times of folding is ≥ 1200 times, and the corrosion resistance is equivalent to that of F4.
(6) The screw lifting structure is adopted, the opening and closing torque is large, and the stability is good.
