“ASTEN” Pneumatic Cylinder Operated Wafer Type Knife Gate Valve.
Knife gate valves are specialized industrial valves designed for applications where the control or isolation of abrasive and viscous media is required. These valves are recognized for their unique, knife-like disc that acts as a gate to control the flow of fluids. Knife gate valves are named for their distinctive gate, which is sharp-edged and typically made of metal or a resilient material. The gate is positioned in the flow path and operates perpendicular to the flow direction. When the valve is open, the gate is lifted, allowing fluid to flow through. Closing the valve involves lowering the gate to block the flow entirely.
