Description
The Mueller Industries AE18358 Pressure Relief Valve is a safety control that regulates internal pressure by releasing excess buildup from refrigerant or fluid lines. It operates through a spring-loaded internal mechanism that opens when system pressure reaches 300 PSI, allowing controlled discharge to prevent overpressure conditions. It is installed using 3/4″ x 3/4″ NPTFE x NPTFI threaded connections and positioned on pressurized piping sections to maintain safe operating limits. This arrangement supports system protection, reduces stress on connected assemblies, and ensures stable pressure balance within HVAC systems used in refrigeration and cooling applications.
