Overview
Pneumatic film lining fluorine regulating valve
Product Details
Pneumatic membrane PTFE single seat control valve is controlled instrument in the execution unit. It consists of pneumatic diaphragm actuator and direct single seat of fluorine plastic valve of two parts. Since the valve wetted parts are high-pressure injection molding process, lining has the capability to corrosion and aging of FEP (F46), and the use of PTFE bellows seal, so that the valve is widely used in chemical, petroleum, metallurgy, medicine, power and other industries in the process of acid and alkali corrosion medium and toxic and volatile gas and liquid medium control.
