Featuring 2-inch inlet and outlet connections, a 30 PSI pressure setting, and a 3,815,000 BTU/hr relief capacity, it is integrated into HVAC systems working hot water boilers and hydronic heating equipment. The valve installs on the designated pressure relief connection and operates automatically whenever system pressure exceeds the preset limit. By maintaining controlled pressure conditions, it supports safeguard connected equipment, supports stable operation, and reduces the risk of pressure-related damage.
