ZJHPF46 pneumatic membrane lined tetrafluoroethylene (F46) single-seat control valve is a corrosion-resistant through single-seat control valve. The valve body wall and the valve inner components in contact with the fluid are all made of high-pressure injection molding technology, lined with corrosion-resistant and aging-resistant polyethylene fluoride (F46), and sealed by PTFE bellows. It is widely applied to the control of acid, alkali and other strong corrosive media and toxic and volatile gases and liquids.
Characteristic
1, corrosion resistance. It is almost capable of corrosion of all media, including concentrated nitric acid and aqua regia.
2, good sealing performance. The bellows and packing are double sealed to ensure no leakage.
3, small leakage. Because the valve core and valve seat adopt soft seal, ensure no leakage.
4, equipped with HA actuators, large output and compact structure.
The product conforms to GB/T4213-92.
