The slow-closing check valve BX300X produced by Boshi Valve is an intelligent valve installed at the pump outlet of high-rise building water supply systems and other water supply systems to prevent media backflow, water hammer, and water impact. The BX300X slow-closing check valve combines the functions of an electric valve, check valve, and water hammer eliminator, effectively improving the safety and reliability of water supply systems. It integrates the technical principles of slow opening, rapid closing, and slow closing to eliminate water hammer, preventing the occurrence of pump-start and pump-stop water hammer. Simply operate the pump motor's start/stop button, and the BX300X slow-closing check valve will automatically open or close according to the pump operation procedures. It features large flow capacity and minimal pressure loss.
Slow-closing silent check valve BX300X Installation and debugging
1. The BX300X slow-closing check valve can be installed horizontally or vertically.
2. Before installation, clean any debris inside the pipeline network to ensure the valve functions properly.
3. During installation, ensure the arrow direction on the valve body aligns with the water flow direction.
4. When the BX300X slow-closing check valve leaves the factory, the needle valve and control valve are fully closed. During use, rotate the needle valve counterclockwise 2.5 turns and open the control valve (ball valve) halfway. If water hammer occurs, slightly close the control valve and open the needle valve counterclockwise to eliminate the water hammer phenomenon.
