Silence Check Valve 
 
Brief introduction:
Silence check valves consist of valves body, seat, diversion shuttle, disc, bearing and spring etc.  The bore is flow-line designed so pressure loss is very little. The disc's stroke is very short and when stop the pump the valves can close quickly and prevent the great noise from water-hammering so the valves can close quietly without any noise .It is widely used in feeding/draining system, fire protection and heat supplying system, and it is installed at the outlet of the pump to prevent backward fluid's and water-hammering's damage to the pump.
