The Red Dot 71R8080 OEM Externally Equalized A/C Expansion Valve is designed for mobile air conditioning systems that require accurate refrigerant control under varying load conditions. Externally equalized valves sense evaporator outlet pressure through a dedicated equalizer line, allowing precise superheat control when evaporator pressure drop is present.

This valve is commonly referenced as Truck Air 12-3025A / MEI 1620 and features a compact “peanut” style body. With 10-inch equalizer and capillary tubes, male O-ring inlet and outlet connections, and a 1½ ton rating, the 71R8080 is widely used across on-highway, agricultural, and off-highway HVAC applications.
