The wide application of stainless steel knife gate valve stems from its own characteristics, first of all, its sealing effect is good, the U-shaped gasket has good elasticity; second, its full path design, through the ability to be strong; again, its brake effect is good, can effectively solve the leakage phenomenon containing block, particle and fiber media gate; Finally, because of its convenient maintenance,

    Replace the valve seal without removing the valve. When the knife gate valve closes, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the gate is pressed to the other side of the valve seat to ensure the sealing surface by the medium pressure. This is the self seal. Most gate valves are forced seals, that is, when the valve is closed, to rely on external forces to force the gate pressure to the seat to ensure the sealing surface of the seal.
