Micro-resistance slow-closing check valve

HH44X micro-resistance slow-closing Check Valve is used in water supply and drainage pipelines. It is installed at the outlet of the water pump to prevent medium backflow and eliminate destructive water hammer. It can also effectively reduce the water hammer pressure when the valve is closed, ensuring the safe operation of the pipe network. It has the characteristics of light valve disc, large opening, significant power saving effect, small fluid resistance, novel design of water hammer elimination mechanism, stable and reliable sealing performance, wear resistance, long service life, smooth operation, no vibration, no noise, etc. 

Check valve refers to a Universal Valve that relies on the flow of the medium itself to automatically open and close the valve disc to prevent the backflow of the medium. It is also called a check valve, one-way valve, reverse flow valve, and back Pressure Valve. The check valve is an automatic Special Valve. Its main function is to prevent the backflow of the medium, prevent the pump and drive motor from reversing, and release the container medium. Check valves may also be used on lines supplying auxiliary systems where the pressure may rise above the system pressure.
