Beside the range RFKA (thermostatic expansion valves with interchangeable orifices) and RFGB (thermostatic expansion valves with fixed orifice) starting from April 2015 a new family of valves RFGD is available, that can be considered a natural evolution of the range RFGB. Sanhua authorised dealers in UK: Thermofrost Cryo Plc and Hawco Limited.
RFGD valves have fixed orifices, a straight layout, solder ODF conections and are available for 5 refrigerants types included R410A. With a capacity range from 12.3 kW to 45kW (conditions: R410A, Condensing temperature: 38°C; evaporating temperature +4,4°C; Liquid temperature 37°C Static Super Heating: 3,5K).
Besides to a wide range of customising models there are 48 standard RFGD models that will be managed as standard product with a stock in the European warehouse.
RFGD series thermostatic expansion valves are used to adjust mass flow of refrigerant into the evaporator while controlling the refrigerant´s superheat at the outlet of the evaporator. They can be used for various refrigerants under all working conditions. Typical applications are refrigeration systems like commercial refrigerators and freezers, icemakers,
dehumidifiers as well as air conditioners at various evaporation temperatures.
