All plastic diaphragm valve

summary:

The all plastic diaphragm valve is a special form of valve with a shut-off function. Its opening and closing components consist of a steel valve disc and a diaphragm made of soft materials (rubber and fluoroplastic composite), which separates the inner cavity of the valve body from the inner cavity of the valve cover to achieve the purpose of cutting off the medium inside the pipe.

1. The valve body material should be made of PPH, RPP, PE, PVDF, CPVC, UPVC raw materials. The diaphragm is a combination of EPDM diaphragm with high toughness and FEP diaphragm processed by injection molding. The central valve stem assembly should be made of stainless steel and steel.

2. The connection specifications between the valve body and the pipeline must comply with standards such as DIN, GB, ASTM, JIS, etc., to achieve unified standard requirements for the overall pipeline system.

3. The design and testing of the valve strictly comply with Q/BT01-1999
