Manual knife gate valve, which uses a gate or wedge-shaped disk to control the flow of fluid through a pipeline valve type. The gate is manually operated by turning a lever or wheel that raises or lowers the gate to open or close the valve. The gate has a sharp edge, hence the name "knife gate", which 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 gate allows it to effectively cut off and shut off the flow of solids.
