Description
Emerson Flow Control (Alco) 046692 Power Assembly is a thermostatic expansion valve accessory, which is used in R-502 refrigerant systems with a 10-foot capillary tube and sensing bulb. It is linked to the expansion valve body and measures the temperature of the evaporator outlet to control refrigerant flow depending on the thermal conditions. This assembly is used in commercial cooling and freezing equipment in practical applications of HVAC systems and refrigeration to assist in maintaining the correct superheat and effective heat uptake in the evaporator.
