is engineered for precise refrigerant flow management in heat pump applications

Easy Calibration: Top-mounted pilot adjustment screw allows for precise flame impingement on the thermocouple

the setpoints of 255 PSI and 444 PSI are specifically engineered for high-pressure refrigerants like R-410A

making it the preferred solution for installations where the radiator or convector is enclosed or located in a way that prevents accurate ambient air temperature sensing at the valve head

Easy Serviceability: Designed for routine inspection and quick clearing of biological growth or debris within the drainage path
