    Product description

    Knife-shaped gate valve needs small space for installation with low working pressure and low price, and sundries are not easy to be stacked。

    Product features

    1. Lift type sealing surface of gate valve is adopted to strike off the adhesion on the surface and automatically clean the sundries

    2. Stainless steel gate plate can prevent sealing leakage caused by corrosion; 

    3. Hard alloy metal sealing surface can ensure the sealing and wear-proof performance and requirement; 
     
    4. As the sealing surface of valve body has no groove set, there is no residuals produced contributing to ensure flexible opening;
     
    5. Short structure, saving raw material, enough installation space to support pipe strength.
