What is slow closing check valve

The slow-closing check valve is an intelligent valve installed at the water pump outlet of the water supply system of high-rise buildings and other water supply systems to prevent medium backflow, water hammer and water hammer. The valve has three functions of electric valve, check valve and water hammer eliminator, which can effectively improve the safety and reliability of the water supply system. Integrate the technical principles of slow opening, quick closing and slow closing to eliminate water hammer to prevent the occurrence of water hammer when the pump is turned on and when the pump is stopped. Just operate the water pump motor on and off button. The valve can be opened and closed automatically according to the operation rules of the pump, with large flow and small pressure loss. Suitable for valves below 600 caliber. The hydraulic control valve is a valve controlled by water pressure. The hydraulic control valve is composed of a main valve and its attached conduit, pilot valve, needle valve, ball valve and pressure gauge. According to different purposes, functions and places, it can be evolved into remote control float valve, pressure reducing valve, slow closing check valve, flow control valve, pressure relief valve, hydraulic electric control valve, water pump control valve, etc.
