Knife Gate Valve Working Principle
The wiper between the valve body and bonnet of the knife gate valve china prevents solid particles from entering the bonnet.

In addition, the advantage of the structure is that the valve body diameter without grooves, the medium will not be blocked, and has a full diameter flow characteristics, suitable for the use of powder and particle media in the pipeline. Its sealing structure can be divided into soft seal, hard seal structure. Sealed valve seat is designed with movable structure, with anti-wear and automatic compensation function, thus longer life.In the process of closing and opening the valve seat and the gate plate have been close to the movement, so that the valve opening and closing force is stable.
