KNIFE GATE VALVE MANUFACTURERS IN INDIA

Speciality Valve is one of the trusted Knife Gate Valve Manufacturers in India with high-performance valves for handling thick, heavy, and abrasive media. Our knife gate valves are rugged in nature, easy to use, and provide efficient sealing performance even under extreme industrial conditions.

Why Is It Necessary?

Knife gate valves are needed in slurry, pulp, or viscous fluid processing applications. Knife gate valves are used to cut through media using a sharp-edged gate, thus perfect for where normal gate valves get clogged or damaged.

Major Components of Knife Gate Valve:

1) Valve Body: This encloses the gate and offers the structural component
2) Gate (Knife): Sharp-bladed piece cutting through flow media
3) Seat: Provides tight shut-off and leak prevention
4) Packing Gland: Avoids leakage around the gate
5) Actuator: Hand, pneumatic, or electrical actuator to operate the valve

Working of Knife Gate Valve:

Knife gate valves function through the process of lifting or dropping a narrow, sharp-edged gate into the flow stream. When closed, the gate lies against the seat to create a tight seal that completely closes the flow. When open, the gate swings completely out of the flow stream, allowing unrestricted flow of the media.

Advantages of Knife Gate Valve:

1) Suitable for slurry, pulp, and solid-carrying media
2) Lowest pressure drops in open position
3) Small, compact design for small space
4) Easy to clean and maintain
5) Low cost for big pipe sizes

Functions of Knife Gate Valve:

1) On/off control
2) Isolating the flow of pipes
3) Well suited for applications with high solid content
