Abstract
The invention relates to a valve assembly for a refrigeration system of the modulating kind used for controlling the flow of refrigerant through the evaporator. The difference between the inlet and outlet temperatures of the evaporator is utilized to control the superheat but the evaporator inlet temperature taken alone is utilized to set different ranges for the valve actuator temperature to accomodate different operating conditions.
