Knife Edge Gate Valve Supplier in India

Speciality Valve is a trusted Knife Edge Gate valve supplier in India. We supply valves to areas like Dubai, Milan and Florence.

A knife edge gate valve is a type of gate valve distinguished by a sharp-edged gate to cut through and effectively shut off flow in applications where a tight seal is required. These valves are often used in industries dealing with viscous fluids, slurries, powders, or liquids containing solids due to their ability to prevent clogging and provide a tight shut-off.


Features of Knife Edge Gate Valve:

1. Gate Design: The gate of a knife edge gate valve has a sharp, knife-like edge that cuts through the fluid, ensuring a tight seal when closed and minimizing the risk of clogging.

2. Bidirectional Sealing: Knife edge gate valves are designed to seal bidirectionally, meaning they can effectively block flow in both directions.

3. Full Port Design: These valves typically have a full port design, allowing unobstructed flow when fully open.

4. Throttling Capability: While primarily designed for on-off service, some knife edge gate valves offer limited throttling capability.


Working Principle:

The working principle of a knife edge gate valve is centered around its unique gate design, which features a sharp-edged blade-like structure. When the valve is in the open position, the gate retracts fully into the valve body, allowing unimpeded flow of fluid through the full port of the valve. As the valve is actuated to close, the gate moves downward, guided by the valve body, until its sharp edge makes contact with the valve seat.

In the closed position, the knife edge gate creates a tight seal against the valve seat, effectively cutting through any fluid or debris present in the flow stream. This design minimizes the risk of clogging and ensures a secure shut-off, even in applications involving viscous fluids, slurries, powders, or liquids containing solids. Additionally, the bidirectional sealing capability of the knife edge gate valve means it can effectively block flow in both directions, enhancing its versatility and reliability in various industrial applications.
