Features

A WCB Pneumatic Knife Gate Valve is a heavy-duty, pneumatically actuated gate valve specifically designed for shut-off and isolation of slurries, particulate matter, powders, and viscous fluids. Unlike conventional gate valves that rely on a wedge-shaped gate, the knife gate valve features a sharp, beveled gate (blade) that cuts through thick, fibrous, or particle-laden media to achieve a positive seal.

The valve is constructed from WCB (Weldable Cast Carbon Steel) material, providing excellent strength and durability for demanding industrial environments.

Sharp gate (knife edge) – Cuts through thick slurries, fibrous materials, and particulate matter

Unobstructed flow path – No body cavity — eliminates solids accumulation and plugging

Pneumatic actuation – Fast operation (1-5 seconds), remote control capable, failsafe options available

WCB carbon steel construction – High strength, excellent durability for mining and industrial service
