HH44X micro-resistance slow closing check valve product overview
The micro-resistance slow closing check valve is used for water supply and drainage pipe, which is installed at the outlet of the water pump to prevent the countercurrent of the medium and eliminate the destructive water hammer, and effectively reduce the water hammer pressure of the valve to close to ensure the safe operation of the pipe network. The utility model has the advantages of light valve flap, large opening degree, remarkable energy saving effect, small fluid resistance, novel design of a water hammer eliminating mechanism, stable and reliable sealing performance, wear resistance, long service life, stable operation, no vibration and no noise.
