Description
Xylem-McDonnell & Miller 250-3/4-60 Relief Valve is a pressure safety component used in hydronic heating systems to control excess internal water pressure. It operates through a spring-loaded mechanism that opens automatically when system pressure reaches 60 PSI releasing water to prevent overpressure conditions and maintaining safe operating limits. The 3/4″ NPT threaded connection allow secure integration into piping lines for stable sealing and flow discharge in HVAC systems. It is placed on boiler or hydronic loop sections where it directly interfaces with the pressure circuit. It ensures controlled pressure regulation system protection from pressure spikes and stable operation during continuous heating cycles.
