Unidirectional Knife Gate Valve Supplier in UAE
UAE Valves is leading Unidirectional Knife Gate Valve Supplier in UAE, providing top-performing flow control solutions designed for challenging applications. Our unidirectional knife gate valves are built to process thick fluids, slurries, and viscous media in processes that demand close shut-off and consistent operation. With heavy-duty construction, best sealing performance, and technical support, UAE Valves is the go-to provider for knife gate valves in the region.
Unidirectional Knife Gate Valve
Unidirectional knife gate valve is an industrial valve used for controlling media in only one direction. It includes a sharp-cutting edge that slices through solid or semi solid and is, therefore, best applied in slurry, pulp, wastewater, or other abrasive application handling. Since it has unidirectional applications, tight closing from one direction only is available, normally in the downstream position, to seal against backflow in certain situations.
Key Components
Valve Body – Encloses the internal components and attaches to the pipeline
Gate (Knife) – A horizontal, sharp-edged plate that travels vertically to regulate flow
Seat – Offers a sealing surface for the gate to cut off flow
Stem – Links the handwheel or actuator to the gate
Packing Gland – Seals the stem region to avoid leakage
Actuator/Handwheel – Controls the gate's motion
Working Mechanism
The valve works by raising or lowering the gate through a handwheel or actuator. When the gate is raised, media passes through the open valve. Upon closing, the gate bears on the seat to close off flow in the intended direction. The sharp edge of the gate enables it to slice through solids, resulting in a clean and complete shut-off. As the valve is unidirectional, it only seals well when mounted in the proper flow direction.
