Knife Gate Valve

Knife Gate Valve

Specializing in the production of knife gate valves, covering various actuation methods such as manual, pneumatic, and electric. The valve body features a wear-resistant sealing design and an unobstructed flow path, suitable for working conditions including slurry, tailings mud, and sewage discharge. The product is compact in structure, flexible in operation, and supports non-standard customization.

Knife gate valves (also known as slurry valves) feature a slim gate structure. The internal flow path of the valve body is straight and unobstructed, making it particularly suitable for pipelines conveying media containing solid particles, slurry, fibers, and other substances. Compared with conventional gate valves, knife gate valves offer advantages such as compact size, lightweight design, low opening and closing resistance, and reduced risk of jamming, making them core control valves in slurry pipelines across mining, environmental protection, and metallurgical industries.
