KRVR Silent check valveDetailed product description：

The KRVR silent check valve is mainly composed of main components such as valve body, valve seat, valve disc, bearing, and spring. The internal water flow path adopts a streamlined design, with minimal head loss. Compared with similar check valves, it is about 1/2-1/3. At the same time, when the pump is stopped, its valve disc closing stroke is very short, and it has the characteristic of short structural length, which can quickly close, avoid water hammer and prevent huge water hammer sound, forming a silent effect.

This valve is mainly suitable for water supply and drainage, fire protection, HVAC, chemical, power plant, metallurgy, petrochemical and other systems. It can be installed at the outlet of the water pump to prevent backflow and water hammer damage to the pump.
