Advantages of a Knife Gate Valve 1. The bottom of the ram is a U-shaped sharp knife edge, which can scrape the adhesive on the sealing surface and quickly cut off the fluid medium 2. The fine grinding and polishing treatment of the ram surface not only obtains better sealing effect, but also effectively protects the service life of the packing and valve seat. 3. The guide block on the valve body makes the ram move correctly, and the extrusion block ensures the effective sealing of the ram.
