KRVZ Silent check valveDetailed product description：

The KRVZ silent check valve is mainly composed of main components such as valve body, valve seat, guide body, valve disc, bearing, and spring. The internal water flow path adopts a streamlined design, with minimal head loss. At the same time, when the pump is stopped, the valve disc switch stroke is very short, which can be quickly closed to prevent huge water hammer and water hammer sound, forming a silent effect. This valve has two types: metal hard seal and metal to rubber soft seal. It 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.
