The thermal expansion valve is used to egulate the supply of liquid refrigerant in the evaporator. The supply is controlled by the superheat of the refrigerant so this valve is especially suitable for the supply of refrigerant liquid in the dry evaporator, because the superheat of the refrigerant at the outlet of the dry evaporator is proportional to the load of the evaporator.
Large evaporation temperature range.
Interchangeable flow port components for easy inventory, pairing, and maintenance.
The installation of the thermometer bulb is convenient, and there is good heat transfer effect between the pipeline and the thermometer bulb.
The valve core and valve body are made of wear- resistant alloy, with a long service life.
Superheat regulation, performance stable.
