Characteristics and Notes of Stainless Steel Knife Gate Valves

The stainless steel knife gate valve adopts knife wedges, which has good shearing effect. It is suitable for slurry, powder, fiber and other uncontrollable fluids, and is widely used in papermaking, petrochemical, mining, drainage, food and other industries. A variety of valve seats can be selected, and electric or pneumatic actuators can be equipped according to the on-site control requirements to realize the automatic operation of the valve.
 


Characteristics of Stainless Steel Knife Gate Valves

• The sealing effect is good, and the U-shaped gasket has good elasticity.
• The stainless steel knife gate valve has full bore, and strong passing capacity.
• The cutting effect is good. It can effectively solve the leakage of massive, granular and fibrous media after the valve is closed.
• The valve can be repaired without dismantling, which is convenient for maintenance.

Notes of Stainless Steel Knife Gate Valve

• The opening and closing part of the stainless steel knife gate valve is the wedge. The movement direction of the wedge is perpendicular to the fluid direction. The knife gate valve can only be fully opened and closed, and cannot be adjusted and throttled.
• When the stainless steel knife gate valve is closed, the sealing surface can be sealed only according to the medium pressure, that is, press the sealing surface of the gate to the valve seat on the other side according to the medium pressure to ensure the sealing of the sealing surface, which is called self sealing.
• Most knife gate valves adopt forced sealing. When the valve is closed, the wedge should be forced to the valve seat by an external force to ensure the sealing of the sealing surface.
