Wesdom’s Pneumatic Knife Gate Valve

A pneumatic knife gate valve uses compressed air to move a flat blade (or gate) that opens or closes the flow of liquid or material. It is especially effective in systems handling thick liquids, slurries, or solid-filled media.

Key characteristics:
Air-powered operation – Uses compressed air for actuation, eliminating manual turning.
Flat blade mechanism – A sharp-edged gate “cuts” through heavy or solid-filled flow, ideal for sludge and slurry.
Automatic movement – Opens or closes as air pressure drives the piston inside the cylinder.
Main components – Pneumatic actuator (air cylinder), solenoid valve (air direction control), air distribution valve, and optional manual control device.
Industry applications – Widely used in wastewater treatment, mining, pulp & paper, and bulk material handling.
