ELECTRONIC EXPANSION VALVE, POLYHEDRA LINE
Castel step-motor expansion valves series 271, 272, 273 regulate
the flow of the liquid refrigerant into evaporators by modulating
the valve shutter position in a calibrated orifice, allowing a wide
capacity regulation range.
Accessories for use with the following ASHRAE 34:2019 refrigerants, Class A1, A2L, or A3:
HFC (R134A, R32, R404A, R407C, R410A, R507)
HFO (R1234YF, R1234ZE)
HFO + HFC (R448A, R449A, R450A, R452A, R452B, R454A, R454B, R454C, R455A, R513A, R515A, R515B)
