Silent check valve Hydraulics-based contouring for
better streamlined design Internal design with flow guide ensures
minimum pressure loss. Muting check valve installed in the pump outlet
at the back of the water before the first quick closure to avoid water
hammer, water hammer and broken flat impact in order to achieve the
purpose of silence, prevent backflow and equipment protection. Mute
check valve is widely used in water supply and drainage, fire
protection, HVAC, industrial systems.
