Quick Close Anti Water Hammer Non Slam Check Valve For Clean Water / Fire Fighting System

Description:

Non Slam Check Valve has very short face to face distance, closing speed is so quick up to max 0.2sec and the stroke is only about 20% of valve bore diameter. The hydrodynamic design with spring can ensure non slamming and minimize the water hammer. The advance diffuser design can maintain the streamline flow and reduce the water head loss to save pumping power. Overall it has a very low headloss and strong capability to minimize water hammer.

Features:

    NSCV is used against water reverse flow suddenly and protects pump and other devices from water hammer harmness.it is mainly used for clean water.

    Closing speed is so quick up to max 0.2sec and the stroke is only about 20% of valve bore diameter. Hydrodynamic design with spring ensure non slamming and to minimize the water hammer.

    Advance diffuser design maintains the streamline flow and reduces the water head loss to save pumping power

    Sphere disc head design gives lower flow resistance coefficient than flat type.

    Powder fusion epoxy coating NSF certificated.

    Bronze bushing can reduce the stem wearing while working and last the service time.

   Choosing the suitable NSCV into working,can return the investment around one year by pumping energy saving
