Thermo Expansion Valves
Alco Controls offers a full range of thermo-expansion valves for commercial refrigeration applications
Alco thermo-expansion valves control the superheat of refrigerant vapor at the outlet of the evaporator. They act as a throttle device between the high pressure and the low-pressure sides of refrigeration systems and ensure that the rate of refrigerant flow into the evaporator exactly matches the rate of evaporation of liquid refrigerant in the evaporator. Thus, the evaporator is fully utilized and no liquid refrigerant may reach the compressor.
