Introduction to ZJHPF46 Pneumatic Thin Film Fluorine lined Single Seat Regulating Valve: ZJHPF46 Pneumatic Thin Film Fluorine lined Single Seat Regula
Product details
ZJHPF46Pneumatic thin film lined fluorine single seat regulating valveIntroduction:
ZJHPF46The pneumatic thin film lined fluorine single seat regulating valve is a PTFE bellows sealed valve. It consists of two parts: a pneumatic thin film actuator and a straight through single seat fluorine lined plastic valve. Due to the high-pressure injection molding process used for the part of the valve that comes into contact with the medium, it is lined with corrosion-resistant media (such as hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid, etc.) and aging resistant polytetrafluoroethylene (abbreviated as PTFE)F46）The valve is widely used in industries such as chemical, petroleum, metallurgy, pharmaceuticals, and power for process control of highly corrosive media such as acids and alkalis, as well as toxic and volatile gas and liquid media, due to its use of polytetrafluoroethylene bellows for sealing
ZJHPF46Pneumatic thin film lined fluorine single seat regulating valveproduct overview:
ZJHPF46Pneumatic fluorine lined regulating valve and corrosion-resistant pneumatic regulating valve are a type of corrosion-resistant straight through single seat regulating valve. The inner wall of the valve body and the components inside the valve that come into contact with the fluid are both high-pressure injection molded, lined with corrosion-resistant and aging resistant perfluoroethylene propylene（F46）It is also sealed with polytetrafluoroethylene bellows.
ZJHPF46Pneumatic thin film lined fluorine single seat regulating valvecharacteristic:
1Corrosion 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. The product complies withGB/T4213-92.
Applicable scenarios:
Pneumatic fluorine lined regulating valves are widely used for controlling highly corrosive media such as acids and alkalis, as well as toxic and volatile gases and liquids.
