Kunkle Valve 0537-G01-HM0100 Valve 322838-752 providing a secure friction fit

providing a secure friction fit that maintains HVAC airflow optimization without significantly increasing static pressure or restricting the combustion air supply

meeting rigorous thermal endurance standards for long-term stability

plug-and-play installation that minimizes wiring errors and labor time during commissioning

This 100F manual reset limit switch acts as a primary thermal safeguard

A trip usually indicates that the net oil pressure (pump outlet minus suction pressure) has not reached the setpoint within the 60-second window

Kunkle Valve 0537-G01-HM0100 Valve 322838-752 providing a secure friction fitThe Kunkle Valve 0537 G01 HM0100 is an industrial grade ASME Section IV pressure relief valve specifically engineered for low pressure hot water boilers, heat exchangers, and steam generators. This 1 1 2" FNPT x 2" FNPT valve is factory set at 100 PSI, delivering a substantial 9,146,296 BTU h (9,146 lb h) discharge capacity to ensure system safety during thermal expansion or over firing conditions. Built with a robust bronze B584 alloy 84400 seat and
