Description
The Watts F278450 2″ Pressure Relief Valve is a safety control valve that is used to control excess pressure in high-capacity heating equipment. It is rated 9,970,000 BTU with a discharge capacity of 174A and a set pressure of 100 PSI and is installed on boilers, water heaters, and closed-loop systems. In the HVAC systems, the valve opens automatically when the internal pressure is too high to ensure safety, and fluid is released to save the appliance and the piping it is attached to. Its use contributes to the controlled operation, prevents mechanical failure, and provides safe pressure conditions in commercial and industrial installations.
