HH44XMicro-resistance slow-closing check valveIt consists of valve body, valve cover, valve flap, valve spindle andcontrol valveIt is installed at the outlet of water pump to prevent the medium from backflow and eliminate destructive water hammer, and can effectively reduce the water hammer pressure of the valve closure, which can guarantee the safe operation of the pipeline network. It is characterized by light valve flap, large opening, small fluid resistance, novel design of water hammer elimination mechanism, reliable sealing, long service life, smooth operation, no vibration, no noise and so on.

Product Features
