thermal expansion valve for R22 R134A R407A

Specifications

thermal expansion valve

General

SM(E),ST(E) series thermostatic expansion valve is a new design. It is an essential part in the refrigeration and air-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 charge method and suits for air-condition,refrigerated cabinets freezer,dehumidifier etc.

Superheat adjusting

After removal of the seal cap,the adjusting stem can be turned.If it is turned clockwise,increase superheat,if it is turned counterclockwise,superheat will decrease.For each turn of the adjusting stem,the superheat will increase or decrease by about 4K.Set superheat 3.5K when exit factory.
