The Russian factory of refrigeration components Frigopoint, announced the performance values and correction factors for the FP-ERV electronic expansion valve for the new 448A / 449A refrigerants. The new refrigerants have a lower global warming potential (GWP), are non-flammable and are therefore classified in safety group A1. The rated capacity of the FP-ERV valve is from 0.23 to 17.1 kW. The data are shown in the table:
