Silence Check Valve
Silence Check Valve Brief Introduction:
The silence check valve is composed of a valve body, seat, guide shuttle, disc, bearing, and spring. Its flow-line design ensures minimal pressure loss. The short stroke of the disc allows quick closure when the pump stops, effectively preventing water hammer noise and ensuring quiet operation. It is widely used in pumping systems, fire protection, and heating systems, installed at the pump outlet to prevent backflow and protect the pump from damage caused by water hammer.
