Description
The Watts F275022 1″ Pressure Relief Valve 174A 40 PSI NPTF is used to relieve excess pressure in HVAC systems and prevent unsafe conditions in boiler equipment. It operates on a spring-loaded mechanism that automatically opens when the pressure reaches the set limit and closes when normal levels are restored, which provides controlled discharge. It has a bronze body with female threaded connections, and an automatic reseating design, which ensures safety is well controlled. It assists in avoiding pressure accumulation, assists in protecting the system, and keeps it under stable operation.
