ZMAPF,ZJHPF series pneumatic thin film lined PTFE single seat regulating valveDetailed product description：

ZMAPF pneumatic film lined PTFE regulating valve and ZJHPF pneumatic film lined PTFE single seat regulating valve are corrosion-resistant straight through single seat regulating valves. The 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 anti-aging polytetrafluoroethylene (F46), and sealed with polytetrafluoroethylene bellows. Widely applicable to the control of strong corrosive media such as acids and alkalis, as well as toxic and volatile gases and liquids.

Features:
1. Corrosion resistance. It can withstand corrosion from almost all media, including concentrated nitric acid and aqua regia.
2. Good sealing performance. Double sealing with corrugated pipe and packing ensures no leakage.
3. The leakage is small. Due to the use of soft seals for the valve core and seat, no leakage is ensured.
4. Equipped with HA actuator, it has high output force and compact structure.  
The product complies with GB/T4213-92.
