ZD/RLPF46 electric fluoridation control valve
anti-corrosion straight single-seat control valve. It is composed of a straight-stroke Electric Actuator and a fluoridation control valve body. The electric lining-fluorine control valve is in contact with the body wall of the valve. The valve components are all made of high-pressure injection molding process, lined with F46 that can resist corrosion and aging, and PTFE bellows seal. Electric lined with fluorine control valve is widely used in acid, alkali and other strong corrosive media and toxic, volatile gases and liquids. Its main features are as follows:
1. corrosion resistance. Almost all media (including concentrated nitric acid and aqua regia) are resistant to corrosion.
2. sealing characters can be good. Double sealing with bellows and packing ensures no leakage.
3. a small amount of leakage. Due to the soft sealing of the valve core and valve seat, no leakage is ensured.
4. with HA enforcement agencies, output power, compact structure. The product complies with GB/T4213-92.
