Slow-closing check valve

The slow-closing check valve is installed on the discharge pipelines of pumps in water supply systems of water treatment plants, high-rise buildings, and other water supply systems. It prevents backflow of the medium and mitigates water hammer and hydraulic shock phenomena. This single valve combines the functions of an electric valve, a check valve, and a water hammer arrestor, effectively enhancing the safety and reliability of the water supply system.
