Description
The Watts F274683 Pressure Relief Valve is a safety component used in heating and systems to control excess internal pressure in closed-loop equipment. It features a 3/4″ connection size designed for integration into boiler and hydronic piping assemblies operating up to 100 PSI and 1,695,000 BTU capacity. It opens automatically when pressure exceeds set limits, releasing fluid to maintain stable operation, and reduce stress on connected components within HVAC systems. It is placed in boilers, water heaters, and equipment where thermal expansion occurs during regular heating cycles, supporting controlled pressure regulation across system lines.
