Diaphragm Introduction


Namely, rubber diaphragm , key part of solenoid pulse valves, consists of rivet, air holes and rubber gasket. diaphragm's size is custom-made, besides, we have other material diaphragms, such as: teflon, ptfe, natural rubber etc. 


shore hardness of diaphragm: 50-80, smooth surface, long lifetime, no crack. 


Normal temperature diaphragm: -30℃-100℃ working pressure: 0.8MPa, high temperature diaphragm: 150℃-220℃. 


a) fabric interlayer 

b) Nitrile rubber, natural rubber, neoprene rubber, EPDM rubber, PTFE rubber, etc. 

c) long lifetime > 1 million times 

d) shore hardness: 50-80

e) normal temperature diaphragm: -30 deg.-100 deg.; high temperature: 150-220 deg. 

f) working pressure: 0.8 MPa Good sealing, air tightness, compact structure, smooth surface, flat, no crack and air bubbles.


The size of diaphragm is based on your pulse valves, free sample is available for your quality test.
