Valves Only focuses on performance and quality to give our knife gate valves reliable output even in the harshest of conditions.

Major Parts of a Knife Gate Valve

Valve Body: The main structure that holds the internal components and attaches the valve to the pipeline.

Knife Gate (Blade): The knife-shaped gate that cuts the material upon opening the valve and tight seals upon closure.

Seat: The surface on which the knife gate seats to ensure zero leakage when closing the valve.

Stem: The component which connects the actuator to the knife gate in order to rotate to open or close the valve.

Actuator: The motor, air, or manual handwheel actuator that operates the valve.

Bonnet: Protective cover which supports the actuator and houses the valve components.

Working Mechanism

Knife gate valve work by utilizing sharp gated knife that shear thick, viscous or slurry like material. When the valve is being opened, the actuator raises knife gate and allow material flow to pass through valve. The gate's cut edge shears any solid or heavy material, allowing a free flow. When valve is closed, knife gate is lowered, creating watertight seal to prevent leakage. This is why knife gate valve are ideal for industries dealing with slurries, wastewater and other demanding substance.

Benefits of Knife Gate Valve

Effective Control of Flow: Knife gate valve have been formulated to effectively regulate thick, viscous, or slurry product, making them perfect for those industries handling demanding fluid handling.

Bi-Directional Operating: Knife gate valve can operate in both direction, providing versatility and ease of installation in variety of application.

Durability: Durable material like cast iron and stainless steel are used to manufacture these valve, which work efficiently in severe condition in long run.

Leak-Proof Sealing: The knife gate's edgy closing, which make tight seal, ensures that even in high pressure operations, there is no leakage.

Minimum Maintenance: Having fewer moving parts and a strong build, knife gate valves are less susceptible to maintenance and ensure smooth operation for years.
