CST42Y Automatic Re-Circulating Control Valve (reflux valve) is installed at the outlet of centrifugal pump to provide economic and reliable protection for the centrifugal pump. It can make a few mediums recycle in pumps under load motion, ensure the minimum flow for pumps safety operation and maintain their stable operation. It also can ensure there is no vibration of pumps and cyclic medium refuse to heat up, provide positive stop to outlet line and prevent backflow of medium through the pump outlet. The valve is widely used in industrial fields, such as the outlet of station pumps
