The Watts 0383793 Pressure relief valve is a safety part used in HVAC systems to prevent pressure build up in systems. This iron body valve has a 1-1/2“ NPT connection and the pressure range is 30 to 75 PSI; the specific relief setting is 55 PSI. When the system pressure rises above this set pressure, the valve opens and discharges the liquid to avoid destructive action on the equipment and pipes. This valve is mainly used in different HVAC systems such as boilers, chillers, and closed-loop hydronic systems. Advantages of using this valve include reduction of system hazards through elimination of expensive equipment damages resulting from overpressure, prolongation of system durability, and meeting safety requirements and standards.
