Uni Directional Knife Gate Valve Manufacturer

Valvesonly Europe is the topmost Uni Directional Knife Gate Valve Manufacturer in Germany. A Uni directional knife gate valve is a type of valve that has a gate or “knife” that moves in a single direction to open or close the flow of a fluid. The gate is typically rectangular in shape and moves perpendicular to the flow direction. Uni-directional knife gate valves are commonly used in applications that require a tight shut-off and are especially useful in abrasive or solid-laden fluid systems.

The working principle of a Uni directional knife gate valve is based on the movement of a gate or “knife” within the valve body. When the valve is in the closed position, the gate seals against the valve body, preventing fluid flow. When the valve is actuated, the gate moves away from the body, and fluid flow is allowed to pass through.

In a pneumatic Uni directional knife gate valve, the gate is moved by a pneumatic actuator, which is controlled by a pneumatic control system. When air pressure is applied to the actuator, it drives the gate to the open position. When air pressure is removed, a spring within the actuator returns the gate to the closed position. The design of the knife edge and the seals on the gate and body ensure a tight shut-off in both directions, even when dealing with abrasive or solid-laden fluids.
