Pneumatic actuated knife gate valve manufacturers in India

Speciality Valve is one of the most trusted Pneumatic actuated knife gate valve manufacturers in India that offers high-performance valves to combat slurry, viscous liquids, and bulk materials with less effort. Our valves are specially designed for automation, durability, and efficiency for demanding industrial applications.

Why Required?

Knife gate valves are especially utilized where thick media such as slurry, pulp, ash, or wastewater exist. The pneumatic actuator supports remote and quick operation within plant systems in which manual operation is cumbersome, hazardous, or inconvenient owing to the process conditions or plant design.

Key Components of Pneumatic Actuated Knife Gate Valve:

Knife-type gate (hard-faced steel or stainless steel)

Pneumatic actuator (single acting or double acting)

Valve body and bonnet (cast iron, carbon steel, stainless steel, etc.)

Stem, packing, and gland layout

Position indicators, solenoid valves, and limit switches (optional)

Working of Pneumatic Actuated Knife Gate Valve:

Compressed air operates the pneumatic actuator to drive the gate up or down. When opened, the gate with pointed edge shears through the media and seats solidly to shut off or meter flow. Remote operation is also possible for rapid shut-off, especially in semi-solid or abrasive flows.

Advantages of Pneumatic Actuated Knife Gate Valve:

Ideal for control of slurry, pulp, and semi-solids

Rapid and efficient actuation

Less operator effort and increased safety

Space-efficient and compact construction

Seamless functioning even in corrosive or abrasive conditions

Ease of integration into automated systems

Functions of Pneumatic Actuated Knife Gate Valve:

Shut-off and isolation of slurry and bulk material systems

Process control for wastewater and chemical plants

Emergency shutdown of flow in automated systems

High-cycle applications in paper, food, or mining applications
