A Knife Gate Valve is an industrial valve primarily used for cutting off the flow of fluids. It gets its name from its distinctive knife-like blade or gate, which can cut off fluid flow similar to a blade. Knife gate valves typically feature a simple and compact design, consisting of a flat or blade-shaped valve disc and a valve seat, allowing the disc to slide along the axis of the pipeline to control fluid flow.
Knife gate valves typically have two main operating states:
Open State: In this state, the valve disc is moved inside the pipeline, allowing fluid to flow freely, enabling smooth passage.
Closed State: When there is a need to cut off fluid flow, the valve disc is moved to the closed position within the pipeline, blocking the fluid flow.
Knife gate valves are usually equipped with a manual operating handle or automatic actuation devices to control the position of the valve disc as needed. This type of valve is highly useful in applications requiring rapid shutdown of fluid flow, such as in emergencies or when handling media containing solid particles. They are commonly used in industries like chemical processing, mining, wastewater treatment, power plants, and others.
In summary, a Knife Gate Valve is a type of valve used to shut off fluid flow, with its design and operation suited for industrial applications where rapid flow cutoff or handling media with solid particles is required.
