Silent check valve >>>Back

Overview
The DRVZ type silent check valve produced by our factory consists of valve body, valve seat, fluid guide, valve disc, bearing bush and spring. The internal flow channel adopts streamlined design, the pressure loss is very small, the valve opening and closing stroke is very short, the pump opening and closing stroke is very short, and the pump can be quickly closed when the pump is stopped, preventing the huge water hammer sound and forming a silent effect.
The valve is mainly used for water supply, drainage, fire protection, and HVAC systems. It can be installed at the pump outlet to prevent backflow of the medium and damage to the pump by the water hammer.
