Knife-shaped gate valve rising stem, dark bar two shapes, the material is cast iron, cast steel, carbon steel, stainless steel, fluorine, etc. It is the forced seal, that is when the valve is closed, to rely on external forces forced the Rams to the seat, to ensure that the sealing surface of the sealing. Its driving mode manual, electric, pneumatic, hydraulic, gear, hydraulic, electro-hydraulic and gas-driven approach.
1, lift-gate sealing surface, scraping the sealing surface of the adhesive material, automatic cleanup of debris.
2, stainless steel plate can be sealed to prevent corrosion due to leaks, and the stainless steel rod is durable, Stud closing more rapidly.
3, hard gold seal surface wear resistance and can ensure the sealed request.
Knife-type valve 9 features
4, the valve sealing surfaces without grooves, does not produce accumulation, to ensure open and flexible, the guide can make the RAM right above it sports, four extruded block ensure effective sealing of gate, the muscle strengthening can increase its strength of the design.
5, a short length of structure, materials, installation space can be saved efficiently support pipe strength; triangles also can save raw materials, ensure the required mechanical properties.
6, packing gland on the scientific design, sealed safe and effective, and durable.
KeyWords: Knife Gate Valve
7, can choose any drive mechanism.
8, more than 150 diameter, with fully enclosed structure, opening more effectively and to prevent leakage.
9, Viton seal with seal punch, increase the temperature, and directly Vulcanized rubber seal in the valve body, will not fall off.
