Manual Knife Gate Valve

What is Manual Knife Gate Valve?

A manual blade gate valve is a type of valve that uses a gate or wedge-shaped disc to control fluid flow through a pipeline. The gate is manually operated by turning a lever or wheel, which raises or lowers the gate to open or close the valve. The gate has a sharp edge, hence the so-called “knife gate” that allows it to cut through solids that may be present in the liquid. This type of valve is commonly used in applications where quick shut-off is required, such as irrigation systems, wastewater treatment plants, and industrial process lines. It is also often used in applications where solids are expected to be present in the liquid, as the sharp edge of the door allows it to effectively cut off and close the flow of solids.
