    Description

    Ceramic knife gate valve

    1. Ceramic knife gate valves have one piece integral body design to reduce  flow resistance

    2. Inlet seat and outlet seat are ceramics materials. Because high hardness and high strength of high pure 99% Al2O3 ceramics, Foyo ceramic knife gate valves have much longer service life than general metal seated knife gate valves in similar conditions.
    3. The gates of ceramic knife gate valves are hardened with nitriding treatment, Tungsten carbide T.C. or hard Chrome to improve working performance.
    4. Several structures of ceramic knife gate valves are available on customers' requirement.

    5. The actuation of ceramic knife gate valves can be hand wheel, pneumatic cylinder, electric motor and hydraulic actuator, special requirements are available on customer’s requirement.
