Externally equalized valves are recommended for multi-circuit systems because they account for excessive pressure drops coming from distributors and through the evaporator—externally equalized valves sense the evaporator pressure from the equalizer line connected to the evaporator outlet. In the automatic expansion valve, the spring pressure along with the atmospheric pressure acts on the diaphragm and pushes it down. As a result, the needle also tends to move down away from the seat leading to the opening of the valve. The evaporator pressure pushes the diaphragm in an upward direction. Due to this, the needle tends to move in ...
