Thermostatic Expansion Valves
The reliability and performance of the refrigeration system is heavily dependent upon proper
expansion valve adjustment. Therefore, the importance of maintaining the proper superheat
cannot be over emphasized. Expansion valves are preset at the factory. In typical applications, field
adjustment should not be required unless the valves are replaced or damaged.
