Function of knife gate valve:

The primary function of a knife gate valve is to provide a tight shut-off to isolate or regulate the flow of fluid. It is specifically designed for applications where there may be solid particles or slurry, as it can effectively cut through the media to create a clear passageway. It is often used in situations where other types of valves, such as ball valves or globe valves, may get clogged or damaged.

Features of knife gate valve:

Gate Blade: The knife gate valve features a sharp-edged gate blade that can cut through solids and seal against a resilient seat when closed.
Unobstructed Flow: When fully open, the gate retracts completely out of the flow path, providing unobstructed flow.
Simple Construction: Knife gate valves are typically designed with simple construction, making them relatively easy to install, operate, and maintain.
Bidirectional Sealing: Knife gate valves can provide a tight seal in both directions, preventing any backflow or leakage.
Manual or Actuated Operation: They can be operated manually using a Handwheel or by using an actuator for automated control.

Working of knife gate valve:

The working principle of a knife gate valve involves the movement of a gate blade to control the fluid flow. Here's a step-by-step description of its operation:

Closed Position: In the closed position, the gate blade is lowered and seated against a resilient seat. This forms a tight seal and prevents fluid from flowing through the valve.
Opening the Valve: When the valve needs to be opened, the gate blade is lifted using the valve actuator or manually operated mechanism. As the gate moves up, it retracts into a recessed area, clearing the flow path and allowing the fluid to pass through.
Full Open Position: In the fully open position, the gate blade is completely retracted, providing unobstructed flow through the valve.
Closing the Valve: To close the valve, the gate blade is lowered back into position, sealing against the seat and blocking the flow of fluid.

Middleeast valve is the best Knife gate valve supplier in Dubai and are primarily designed for applications where a tight shut-off is not critical, and the valves are not typically used for regulating the flow rate.
