Product Details
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.
