SVR Global is the top rated Knife gate valve manufacturer in USA providing high-quality valves to the mining, water, and chemical sectors in Washington, Oregon, and Indianapolis. An excellent valve for managing slurries and other viscous fluids is a knife gate valve, which has a sharp-edged blade designed to cut through and scrape off material accumulation on the sealing surfaces.
It is frequently utilised in situations where a tight shut-off is necessary and when there is a lack of available area. The valve is available in a variety of sizes and materials to suit diverse purposes, and it may be operated manually, by pneumatic, electric, or other actuators. When it's open, the fluid flow is restricted; when it's closed, the fluid flow is unhindered.
How does a knife gate valve work?
A knife gate valve operates by using a sharp-edged gate or blade to control the flow of fluids, slurries, or powders in industrial applications. The valve consists of a compact body with a through-going port and a gate, which is typically shaped like a knife. In the open position, the gate allows unobstructed flow, and in the closed position, it seats against the valve's body, forming a tight seal to stop the flow. The gate is actuated either manually or through automated means such as electric, pneumatic, or hydraulic actuators. This design is particularly effective in applications involving slurries and solids, where the knife gate valve can cut through and isolate the fluid flow, making it well-suited for tasks like wastewater treatment, mining, and pulp and paper processing. The minimal pressure drop across the valve and the bidirectional sealing capability contribute to its efficiency in on-off and isolation functions within various industrial settings.

Applications
- Knife gate valves are frequently employed in mining and mineral processing to regulate the flow of slurry and tailings, mixes of water and finely crushed particles.
- Knife gate valves are used in wastewater treatment facilities to regulate the flow of sludge, which is a combination of water and particles.
- Knife gate valves are used in the pulp and paper industry to regulate the flow of pulp, which is made up of a combination of water and wood fibres. They can manage the pulp's high consistency and offer a tight shut-off to stop leaks.
- Knife gate valves are used in chemical processing to regulate the flow of corrosive and abrasive substances.
- Knife gate valves are used in power generation to regulate the flow of materials such as ash slurry in coal-fired power plants.
