  • Description:
  • ZRHPF Electric fluorine lined control valve Feature

    ZRHPF Electric fluorine (PTFE,FEP,PFA) lined control valve is composed of electric actuator,straight through single seat fluoride (PTFE,FEP,PFA) Lined structure. Electric fluorine lined control valve contacted with the corrosive medium adopts the corrosion-resistant, anti-aging PTFE,PEP,PRA, the high pressure lining fluorine plastic process.Electric fluoride (PTFE,FEP,PFA) lined control valve is capable of controlling the flow of acid, alkali, aqua wang and other highly corrosive media, toxic volatile gas and liquid media.Therefore, Electric fluoride (PTFE,FEP,PFA) lined control valve is widely used in chemical, metallurgy, medicine and other industries.
    ZRHPF Electric fluorine (PTFE,FEP,PFA) lined control valve Features as below:
    1. Good corrosion resistance: the inner cavity of Electric fluorine lined control valve body, core, seat are lined with 3mm thick fluorine (PTFE,PEP,PRA) , which can withstand strong corrosive fluid.
    2. Good sealing performance: double sealing with PTFE bellows and packing.
    3. The leakage quantity is little, because the Electric fluorine lined control valve core and seat are soft seal, leakage was far below the national Ⅳ level standard.
    4. High adjustment accuracy: Electric fluorine lined control valve adopts precise and small pneumatic and electric actuators, small in size and light in weight.
