Speciality Valve is a well-known name among Pneumatic Knife Gate Valve Manufacturers In India, providing long-lasting and efficient valves for slurry, pulp, and viscous medium handling in a range of industrial applications. 

A pneumatic knife gate valve is an automatic valve used to isolate or control flow with a sharp-bladed gate powered by a pneumatic actuator for smooth operation in heavy-duty services. 

Components of Pneumatic Knife Gate Valve 

1. Body 
2. Gate/Blade 
3. Pneumatic Cylinder (Actuator) 
4. Stem and Packing 
5. Seat and Seals 

Working Mechanism 

The pneumatic actuator pushes the gate upwards or downwards, enabling or preventing the flow. It operates on compressed air, ensuring quick and reliable action, particularly in automatic systems.
