Product overview

DRVZ silent check valve is mainly composed of valve body, valve seat, guide body, valve disc, bearing, spring and other main parts. The internal flow channel adopts streamlined design with small pressure loss. The opening and closing stroke of the valve disc is very short. It can be closed quickly when the valve and pump are stopped to prevent huge water hammer sound. It has the characteristics of silent closing.

The valve is mainly used for water supply and drainage, fire fighting and HVAC systems. It can be installed at the outlet of the water pump to prevent backflow and damage to the pump by water hammer.
