Check Valve

The check valve is an automatic opening and closing valve that does not require manual operation or other actions. It relies on the flow of the pipeline medium itself to open or close the valve. It is mainly used to prevent the reverse flow control of the pipeline medium. It is also called a check valve. or reverse flow valve. The check valve has only one flow direction, that is, it can only flow along the water inlet and cannot go backwards. When the medium flows backward, the valve disc is closed. Check valves are generally installed in places to prevent the backflow of media when the valve is not closed. For example, a check valve is installed at the outlet of a common water pump to prevent high-pressure water from flowing backward into the water pump, causing the water pump impeller or other components to become loose or damaged due to hydraulic impact, leading to accidents. In short, check valves are used in pipelines or equipment to prevent the backflow of media. Common check valve types include: double-disc swing check valve, rubber disc check valve, ball check valve, etc. Our factory can produce all of them.
