300X Slow closing check valveDetailed product description：

The 300X slow closing check valve is an intelligent valve installed at the pump outlet of high-rise building water supply systems and other water supply systems to prevent medium backflow, water hammer, and water hammer phenomena. The 300X slow closing check valve combines the functions of an electric valve, a check valve, and a water hammer eliminator, effectively improving the safety and reliability of the water supply system. It integrates the technical principles of slow opening, quick closing, and slow closing to eliminate water hammer, preventing the occurrence of water hammer during pump start-up and shutdown. Simply operate the water pump motor on/off button, and the valve will automatically open/close according to the water pump operating procedures, with high flow rate and low pressure loss.
