Rheem 3/8" ODF x 3/8" ODF Thermal Expansion Valve, 1 Ton, External Equalizer

In refrigeration and air conditioning applications, the expansion valves function as crucial valves that modulate refrigerant flow into the evaporator coil based on temperature sensing. These expansion valves are instrumental in the refrigeration cycle, ensuring precise control over the liquid refrigerant entering the evaporator to uphold optimal system performance. Furthermore, the PROTECH™ Type CBBI thermostatic expansion valve is engineered with a balanced port design and integrated check valve assembly, making the expansion valve suitable for residential and small commercial heat pump systems that mandate reliable check valve operation.
