KRVG Silent check valveDetailed product description：

The KRVG silent check valve is mainly composed of main components such as valve body, valve seat, guide body, valve disc, bearing, and spring. The internal passage adopts a streamlined design, and the head loss is about 1/3-1/4 compared to similar check valves. At the same time, when the pump is stopped, the valve disc closing stroke is very short, which can be quickly closed to 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, heating and ventilation, 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. Vertical installation yields better results.
