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.Zero leakage
The unibody casting process is adopted. The inner groove of the valve body is lined with U rubber sealing strip, which is tightly sealed with the edge of the valve plate.

2.No blocking by the slag
There are no grooves at the bottom, making the flow of the fluid medium easy to plug.

3. More durable
The sealing strip design makes valve more durable.

4.Easy to install and disassemble
Small volume, smooth passage, small flow resistance, light weight, easy to install, easy to disassemble

Application:

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