INTRODUTCTION

ADVANTAGES

  • No trachoma

    Precision casting valve body, fine appearance, no trachoma.

  • Good sealing porformance

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

  • Small friction, not easy to deform

    Valve stem is equipped with bearing to reduce friction.

  • Rubber coated PTFE packing seal

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

  • Reliable connection

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

  • IP67 protection level

    The protection level of pneumatic actuator is IP67.

FEATURES

Knife gate valve is also named  slurry valve, mud valve. Its opening and closing part is a gate.The medium is cut by a blade-shaped gate that can cut fiber materials; It rises and falls in the side guide groove, and is pressed against the valve seat by the lugs at the bottom. If a higher medium tightness is required, an O-shaped sealing valve seat can be used to achieve two-way sealing. The knife gate valve has a small installation space, low working pressure, long service life and simple maintenance.

Suitable Medium:Molasses, pulp, sewage, coal pulp, ash, slag water mixture.

Working Temperature: 0℃~80℃

Application field:Chemistry, water treatment, coal power plants, food, paper, petroleum.
