ValvesOnly are the topmost Knife Gate Valve Manufacturers in USA. A knife gate valve is a specific type of industrial valve designed for on-off and isolation applications involving the control of fluids, slurries, or powders. This valve derives its name from the thin, sharp-edged disc or gate that operates as a closure element. Unlike traditional gate valves, knife gate valves are specially designed for applications where a straight-line flow of fluid with minimal restriction is required, and they excel in handling media containing suspended solids, such as slurries.

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.
