The pneumatic film single seat lining fluorine regulating valve is the execution unit in the automatic control instrument. It is composed of two parts of the pneumatic film actuator and the single seat lined fluorine plastic valve. Because the valve contact medium parts are used high-pressure injection molding process, lined with corrosion resistance, aging-resistant poly-ethylene propylene (F46), but also the use of PTFE bellows seal, so the valve is widely used in chemical, petroleum, metallurgy, medicine, electricity and other industries in the acid, alkali strong corrosive medium and toxic, volatile and other gases,

Process Control of liquid medium.

Pneumatic membrane single seat lining fluorine control valve product Features:

1, corrosion resistance: valve body cavity, spool, valve seat, valve stem are 316 stainless steel, capable of acid, alkali, strong corrosion resistance.

2, good sealing performance: the use of poly-ethylene corrugated pipe and filler double seal to ensure no leakage.

3, leakage of small: because the spool, valve seat is a soft seal, the leakage rate is lower than the national level IV standards. 4, the use of light and small multi-spring actuator, small size, light weight, large output force, compact structure, high adjustment accuracy.
