Expansion Valves Thermostatic expansion valve is a component regulating rate of refrigerant flow into the evaporator as governed by the evaporator outlet tube temperature sensed by sensing bulb.
Replace with receiver-drier and complete system evacuation to assure proper system operation. Very important following a compressor failure because if any contaminants remain in system, they will cause the new compressor to fail.
We stockexpansion valves to ship with compressors and again takes pride in supplying quality units.
