expansion valve
General
SM(E),SMJ(E),ST(E),STJ(E) series thermostatic expansion valve is a new design. It is an essential part in the refrigeration andair-condition system. It is equipped between the liquid receiver and the evaporator.By its throttling,the liquid refrigerant under high temperature and pressure changes to the low pressure moist vapor,in the meantime,during the evaporation of low pressure moist vapor in the refrigerating system,heat is absorbed from the surrounding and there temperature is lowered.
It supply many kinds of charge method and suits for air-condition,refrigerated cabinets freezer,dehumidifier etc
Characteristics
