Silence Check Valve
Silence Check Valve
Brief Introduction:
The silent check valve is designed with a body, seat, shuttle, disc, bearing, and spring. Its flow-line design minimizes pressure loss. The short stroke of the disc allows it to close quickly when the pump stops, effectively preventing water hammer noise. It is widely used in water supply and drainage systems, fire protection, and heating systems. It is typically installed at the pump outlet to prevent backflow and damage caused by water hammer.
