Xylem-Bell & Gossett P86596 Hi Temperature Check Valve

The Xylem-Bell & Gossett P86596 High Temperature Check Valve is a flow-control component used to prevent reverse fluid movement in hydronic pumping systems. It operates using a spring-loaded disc that opens under forward pressure and closes when flow reverses maintaining correct circulation direction. It is installed in circulator pump discharge lines, where it supports the stable operation of heating and cooling loops. It is used in HVAC systems, boiler circuits, and chilled water applications to protect equipment performance and maintain system efficiency under high-temperature conditions.
