A knife edge gate valve is a specialized type of gate valve that features a sharp-edged gate with a beveled or knife-like shape. This design allows for precise and efficient control of fluids containing solids, slurry, or other challenging media. Knife edge gate valves are commonly used in industries such as mining, chemical processing, wastewater treatment, and power generation.

Knife edge gate design: The gate of a knife edge gate valve has a sharpened, beveled edge that provides a tight seal against the valve seat. This design enables the valve to effectively cut through and scrape away solid particles or fibrous material present in the fluid, minimizing the risk of clogging or blockages

Bi-directional flow: Knife edge gate valves typically allow for bidirectional flow, meaning they can handle fluid flow in both directions. This feature provides installation flexibility and ease of operation.

Efficient flow control: The sharp-edged gate of a knife edge gate valve allows for precise flow control. When fully open, the gate retracts into the valve body, providing a clear path for unrestricted flow. When closed, the gate forms a tight seal against the seat, ensuring complete shut-off.

Solids and slurry handling: Knife edge gate valves are specifically designed to handle fluids containing solids, slurry, or other abrasive media. The sharp-edged gate helps prevent build-up and blockages, reducing maintenance and improving overall system performance.

Resilient or metal seated options: Knife edge gate valves can be equipped with resilient seats, such as rubber or elastomer, for general applications. For more demanding conditions, metal-seated versions with materials like stainless steel or hard-faced alloys are available to provide enhanced durability and wear resistance.

Actuation options: Knife edge gate valves can be operated manually or automated using various actuation methods, including handwheels, pneumatic actuators, electric actuators, or hydraulic actuators. Automation allows for remote operation and integration into control systems, enhancing efficiency and safety.

Maintenance: Regular maintenance, such as lubrication of the gate and stem, and periodic inspection of the sealing components, is necessary to ensure proper functioning and extend the valve’s service life.
