Types of Pneumatic Operated Knife Gate Valves
- Single Acting Pneumatic Knife Gate Valve – Operates using air pressure in one direction and spring return for closing or opening.
- Double Acting Pneumatic Knife Gate Valve – Uses air pressure for both opening and closing operations, ensuring precise control.
- Wafer Type Knife Gate Valve – Compact and lightweight design suitable for space-constrained installations.
- Lug Type Knife Gate Valve – Allows easy installation and maintenance in pipeline systems with end-of-line service.
- Slurry Knife Gate Valve – Specifically designed for handling abrasive and viscous media like slurry and semi-solid materials.
- Bi-Directional Knife Gate Valve – Enables flow and shut-off in both directions, enhancing flexibility in operation.
How Pneumatic Operated Knife Gate Valves Work
Pneumatic operated knife gate valves are widely used in industrial applications for handling thick fluids, slurries, and solid-laden media. These valves use compressed air to actuate the valve, providing fast and efficient operation.
When compressed air is supplied to the actuator, it moves the gate (blade) up or down to open or close the valve. In double acting systems, air controls both opening and closing, while in single acting systems, a spring mechanism assists in returning the gate to its original position. This automated operation ensures reliable flow control even in demanding conditions.
As a trusted pneumatic operated knife gate valve manufacturer in Mumbai, we offer robust and high-performance valves designed for durability, tight shut-off, and efficient handling of challenging industrial applications.
