Heat expansion valve is a key component of refrigerating system. It is usually mounted between the liquid accumulator and evaporator to allow liquid of high temperature and pressure to become moisturized steam of low temperature and pressure after being throtted. Then the refrigeration is achieved througn the heat being absorbed by the refrigerant in evaporator.
Heat expansion valve control the flow of the valve through regulating the overheating degree at the end of evaporator in order to avoid inadequate use of the surface area of evaporator and prevent sinter being produced on the bottom of evaporator.
Overheating Degree Regulation: Remove the seal nut and turn the regulating leveer one round counterclockwise, and then the overheating temperature decrease by
1. The factory set over heat temperature is 3.5 and the static overheating degree can be ranged 2~8 Basic features
2. The consistent overheating degree allows stable operations of the system;
3. Applicable to the needs of refrigeration and air-conditioning;
4. Temperature of evaporation is ranged-40~+10;
5. Applicable to the media of R12, R22 and R134a;
Note: Special requirements should be informed when placing order.
