Description
The Conbraco Industries 1040705 Hot Water Relief Valve protects heating systems from excessive pressure buildup through automatic discharge mechanisms. This 3/4-inch male inlet by 3/4-inch female outlet brass component opens at a 30 PSI threshold, releasing water or steam to prevent tank rupture or piping damage. A spring-loaded disc seats itself against an orifice until system pressure exceeds calibrated limits in HVAC systems. It threads directly into boiler tappings, water heater ports, or hydronic system manifolds using standard NPT connections. Complies with plumbing codes requiring overpressure protection, resets automatically when pressure normalizes and safeguards property and occupants in potable water heating & closed-loop hydronic applications.
