Danfoss expansion valve thermal expansion valve for regulating the supply amount of evaporator liquid refrigerant. Supply amount is controlled by the degree of superheat of the refrigerant. Therefore, this hair is particularly suitable for supplying the liquid refrigerant in the evaporator dry, because the load is proportional to the degree of superheat of the refrigerant at the outlet of a dry evaporator with evaporator. Features: 1. 1. a wide range of evaporation temperature interchangeable orifice assembly easier inventory, easy to match capacity and easier maintenance. 2. When the working fluid is R22 nominal cooling capacity 0.5-15.5kw (0.15-4.5TR) 3. Available with MOP function valve to prevent excessive evaporation due to pressure cause the compressor motor damage. The patented dual-contact thermal package, quick and convenient to install, has a good heat transfer between the pipe and the bulb. 5. provide special temperature range of valve area.
