The ZJHPF pneumatic fluorine lined regulating valve is a top guided single seat regulating valve, which has the characteristics of simple structure, good sealing performance, large flow rate, and reliable use. An effective and sufficient top guidance system overcomes vibrations at small openings, resulting in a longer effective lifespan. Multiple spring pneumatic thin film mechanisms or electric actuators can be selected.

1、 Overview of ZJHPF Pneumatic Fluorine lined Control Valve

The ZJHPF pneumatic thin film lined PTFE regulating valve is a corrosion-resistant straight through single seat regulating valve,Pneumatic fluorine lined regulating valveThe inner wall of the valve body and the components inside the valve that come into contact with the fluid use high-pressure injection molding technology, lined with corrosion-resistant and aging resistant perfluoroethylene propylene（F46）It is also sealed with polytetrafluoroethylene bellows.

ZMAPF pneumatic thin film lined PTFE regulating valve is widely used for controlling highly corrosive media such as acids and alkalis, as well as toxic and volatile gases and liquids. Its function andPneumatic diaphragm regulating valveSame, but capable of withstanding greater pressure than diaphragm regulating valves.

2、 Characteristics of ZJHPF Pneumatic Fluorine lined Control Valve

1. Corrosion resistance. It can withstand corrosion from almost all media, including concentrated nitric acid and aqua regia.
2Good sealing performance. Double sealing with corrugated pipe and packing ensures no leakage.
3The leakage is small. Due to the use of soft seals for the valve core and seat, no leakage is ensured.
4, equipped withHAExecution mechanism, with high output force and compact structure.
