Product introduction：

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.

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. 

Application:

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