Pneumatic Rising Stem Bi-directional Slurry Knife Gate Valve

Product Description: JZB knife gate valve is a bi-directional sealed knife gate valve designed and manufactured for general industrial industry. The ductile iron valve body adopts the integral casting structure. The left and right sides of the valve body and the bottom of the middle cavity are provided with grooves and equipped with elastic U-shaped sealing strips. When the valve is closed, the disc moves down, and the bottom edge of the disc contacts with the sealing strip to compress the sealing strip into the grooves to achieve the sealing of the valve body and the disc. This design ensures the non blocking closing of the suspended particles.
