Diaphragm choose

1. One piece diaphragm EPDM+PTFE  (Max temperature 120℃)

PTFE diaphragm tablet has high chemical resistancemhigh stability,goof flexiblity.long life,high sealing,no cold degeneration,and not affected by temperature fluctuations excellent performance,whether it is thermal cycle,cold cycle,or steam disinfection system.

2. Single diaphragm EPDM/Silicon/FPM (Max temperature 120℃)

Rubber diaphragm embedded a layer of vulcanized fiber layer enhance its mechanical properties,teh diaphragm in pressure and temperature has high seal stbility.reinforcingfiber hardening in stainless steel bolt,as as to ensure better rubber and metal bond together,

Therefore rubber diaphragm more suitable for use in vacuum environment.

3. 2PC diaphragm EPDM+PTFE  (Max temperature 150℃)

By EPDM and PTFE composed of diaphragm,the characteristics of the diaphragm is the valve is in the closed position,diaphragm itself shape can and body sealing,which reduces the diaphragm tolerance adn prolong the service life of the diaphragm.

Various sanitary tank bottom diaphragm valve configuration
