Description
The Watts F274836 3/4″ Pressure Relief Valve 174A 2,445,000 BTU is a essential part used in boiler and hot water heating systems to protect equipment from excessive internal pressure in HVAC systems. It works by using a spring-loaded mechanism that automatically opens when system pressure exceeds the set limit of 150 PSI, releasing water to prevent damage and restore safe operating conditions. It is used in systems where pressure control is critical. It helps improve system safety, prevent equipment failure, reduce overheating risks and ensure stable, and protected performance in heating applications.
