Check Valve

A check valve is a valve used to control the one-way flow of fluid, also known as a non-return valve. It can prevent fluid from flowing back in the pipeline and is usually used in fluid pipeline systems such as water, oil, and gas. Check valves usually have a simple structure, including valve body, valve cover, valve disc and other components. The flow direction of the fluid is controlled by the opening and closing of the valve disc. Check valves are widely used in industry, construction, water supply, drainage and other fields.
