    Feature:

    1. Knife gate valve opening and closing part is the valve plate, the plate movement direction is perpendicular to the direction of the fluid. Knife gate valve can only be fully open and fully closed, can’t be used for adjusted and the throttle.

    2.The valve plate has two sealing surfaces. The two sealing surfaces of the most common gate valve forming the wedge, the wedge angle various according to the valve parameters, usually is 50. Wedge knife gate valve plate can be made into a whole part , called the rigid gate plate; also be made to that can produce small quantities of deformation in order to improve its production process, to make up the sealing surface angle deviations arising during processing, this plate called resilient plate. The seal can only rely on media pressure to seal, which rely on media pressure to ram pressure to the sealing surface of the other side of the seat to ensure the seal, which is self-sealing. 

    Product Advantages:

    1. Precision casting valve body, fine appearance, no trachoma.

      2. Valve wedge is burnished smoothly 3 times and polished 5 times to ensure the sealing porformance.

      3. Valve stem is equipped with bearing to reduce friction.

      4. Rubber coated PTFE packing seal, which can increase the elasticity and reduce the leakage of upper seal.

      5. U-shaped sealing ring of the seat to ensure the strong conbation between valve seat and body.

      6. Each valve will be tested shell and sealing pressure before leaving factory.

      7. 250 μm epoxy coating, it can effectively prevent corrosion and rust.   

      8. The protection level of electric actuator is IP67.

    Application:

    Paper, petrochemical, mining, drainage, food and other industries
