Rather than design an infinite variety of thermostatic expansion valve sizes to accommodate different capacities for heat removal, some manufacturers use a few standard valve body sizes in conjunction with what other feature?

Correct Answer: Option A — internal needle valve orifices of various sizes to accommodate different heat removal capacities

To accommodate varying cooling capacities without manufacturing entirely different valve bodies, expansion valve manufacturers utilize interchangeable internal cage assemblies or needle valve orifices of differing capacities within standardized valve body housings.
