Product Advantage
Knife gate valves are mainly used in papermaking, chemical fiber, petrochemical, metallurgy, mud, electricity, sewage treatment. In pharmaceutical and other working conditions, the knife gate valve is mainly composed of a valve body and a gate. The material of the valve body is ductile iron, carbon steel and stainless steel, and the sealing surface is made of natural wear-resistant rubber, fluorine rubber, nitrile rubber, and EPDM rubber. And metal sealing, from the structural point of view, the knife gate valve has a compact design, takes up little space, and can effectively support the strength of the pipeline.
There are 3 features as below:
1. The bottom of the gate is a U-shaped sharp blade, which can scrape off the adhesive on the sealing surface and quickly cut off the fluid. medium.
2. The surface of the gate has been finely ground and polished, which not only has a 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 gate move correctly, and the extrusion block ensures the effective sealing of the gate.
