Knife Gate Valve – Key Features & Advantages
Abrasion-Resistant Design
Optional deflection cone redirects abrasive slurries away from the seat, extending service life in mining or wastewater systems.
Through-conduit design minimizes flow turbulence and particle accumulation for clog-free operation.
Precision Flow Control
V-port discs enable precise throttling in pulp & paper or chemical processing applications.
Full-port design ensures unrestricted flow for high-efficiency slurry transport.
Material Versatility
Bodies in cast iron, stainless steel, or abrasion-resistant alloys.
Seats tailored for temperature, pressure, and media compatibility (EPDM, NBR, or hardened steel).
Knife Gate Valve – Robust Solutions for Slurry & Abrasive Media
Knife gate valves are engineered for demanding applications, offering versatile configurations to meet diverse industrial needs. Available in one-piece or two-piece body designs, these valves provide options for rising stem (visual position indication) or non-rising stem, alongside unidirectional or bidirectional sealing with resilient (elastomer) or metal seat rings. Bonnetless designs simplify maintenance, while bolted bonnet variants enhance pressure containment.
Knife Gate Valve
Knife gate valves are available in various designs, one-piece body and two-piece bodies, rising stem and non-rising stem, uni-direction and bi-direction structures, resilient and metal seat rings, bonnetless and bolted bonnet designs. For optional designs, deflection cone could divert the flow of abrasive slurries and protect valve seat from abrasion, V port disc and through conduit design are used for throttling service, per customers’ requirements.
