INSTRUCTIONS
SHF series four-way reversing valves are applicable for heat
pump systems to switch between cooling mode and heating
mode by changing the flow path of refrigerant. Sanhua
reversing valves cover a wide application range suitable for
capacities from 1 ton to 120 tons and refrigerants such as R-22,
R-134a, R-404A, R-407C, R-410A and R-507C.
