Emerson Flow Control (Alco) 053764 Expansion Valve Power Assembly R22

The Emerson Flow Control (Alco) 053764 Expansion Valve Power Assembly is an essential part used with R22 refrigerant in different HVAC systems. It controls the refrigerant of the amount that enters the evaporator so that the rate at which liquid refrigerant evaporates is correct for the efficiency of the system and to stop liquid refrigerant from returning to the compressor. This high precision means that refrigeration systems such as display cases, freezers, ice cream machines, and air conditioning machinery among others can operate at the better possible efficiency.
