Types of Pneumatic Operated Knife Gate Valves
We supply unidirectional and bidirectional pneumatic knife gate valves in CI, CS and SS body construction, with resilient or metal seating, sized for a wide range of slurry-handling pipelines.
Single Acting Pneumatic Knife Gate Valve
Air pressure drives the gate in one direction; spring return handles the opposite stroke.
Double Acting Pneumatic Knife Gate Valve
Air pressure controls both open and close strokes, allowing precise automated operation.
Wafer Type Knife Gate Valve
Compact, lightweight design ideal for tight-space installations between pipe flanges.
Lug Type Knife Gate Valve
Threaded lugs allow easy installation and dead-end service without removing the valve.
Slurry Knife Gate Valve
Specially designed for abrasive and thick media including slurry, pulp, and semi-solids.
Bi-Directional Knife Gate Valve
Provides effective shut-off in both flow directions for greater pipeline flexibility.
How Pneumatic Operated Knife Gate Valves Work
Pneumatic operated knife gate valves are engineered to handle demanding applications involving abrasive slurries, viscous fluids, and solids-laden media. The actuator converts compressed air energy into mechanical motion, enabling precise and efficient operation of the gate blade. This automated functionality eliminates the need for manual intervention, improving operational efficiency while reducing labor costs and downtime in industrial processes.
One of the key advantages of a pneumatic actuated knife gate valve is its ability to provide quick and reliable shut-off performance. The actuator delivers consistent force to move the blade smoothly through the flow stream, ensuring effective isolation even in challenging service conditions. Because the valve can be integrated with control systems, operators can monitor and regulate flow remotely, enhancing process control and overall plant safety.
These valves are widely used across industries such as wastewater treatment, mining, pulp and paper, chemical processing, and power generation. Their robust construction, corrosion-resistant materials, and low-maintenance design make them suitable for harsh operating environments. By combining the durability of a knife gate valve with the speed and automation of pneumatic actuation, these valves offer a dependable solution for modern industrial flow control applications.
Applications
These valves are used in mining, pulp & paper, sugar, chemical processing and wastewater treatment plants where slurry or viscous media must be isolated quickly and remotely.

Frequently Asked Questions
Answers to common questions about pneumatic operated knife gate valves, materials, sizing and selection.
A pneumatic operated knife gate valve uses compressed air to move a flat gate blade, providing automated open/close control for slurry, viscous, and solid-laden pipelines.
Compressed air drives the actuator, which lifts or drops the knife gate blade. In double acting valves, air controls both strokes. In single acting valves, a spring returns the gate to its fail-safe position.
They are widely used in mining, wastewater treatment, pulp and paper, cement plants, power plants, chemical processing, and bulk material handling industries.
Single acting uses air for one stroke and a spring for return. Double acting uses air pressure for both open and close strokes, offering more precise control.
Body materials include cast iron, cast steel, and stainless steel. Gate materials are available in SS 304, 316, 316L, 317, and 317L depending on application requirements.
Standard sizes range from 50NB to 600NB. Custom sizes above 600NB are available on request.
