Exchangable orifice valveis easy to store, maintain and match with the system.
Exchangable orifice 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.
Characteristics
l Constant superheat adjusting performance.
l Rugged stainless steel diaphragm
l Interchangeable cage
l Inlet strainer assembly
l For use on refrigerants 22,134a,407c and 404A/507
l With MOP function
l Safe working pressure of 3.0 MPa
l Maximum bulb temperature is 75°C
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.
