ZJHPF pneumatic fluorine-lined single-seat control valve is a kind of anti-corrosion straight-through single-seat control valve, the inner wall of the valve in contact with the fluid and the components in the valve are made of high-pressure injection molding process, lined with corrosion-resistant, age-resistant polyperfluoroethylene propylene (F46), and PTFE bellows seal. It is widely used in the control of strong corrosive media such as acid and alkali and toxic and volatile gases and liquids.
1. Corrosion resistance. Resistant to almost all media, including concentrated nitric acid and aqua regia.
2. Good sealing performance. Double sealing with bellows and packing to ensure no leakage.
3. The leakage is small. Since the spool and seat are soft-sealed, no leakage is ensured.
4. Equipped with HA actuator, large output force and compact structure. The product conforms to GB/T4213-92.
