HC (R290, R600, R600A, R1270)


These valves are only sold in the model with the ATEX certified coil (A6 suffix), with 9 nozzles assembled for an increasing output from 2 to 36 kW with R290.

Coils with the new FAST LOCK fixing system, series 9300 and 9320, and coils with gear fixing systems, series 9110, 9120 and 9160.
Fast-on connections type DIN 43650/A for coils in series: 9120, 9160, 9300 and 9320; co-moulded cables for series 9110 coils. Protection rating IP65; IP68 for series 9160 coils coupled with series 9155 connectors.
Available voltages; 24 VAC - 50/60 Hz, 110 VAC - 50/60 Hz, 220/230 VAC - 50/60 Hz, 240 VAC - 50/60 Hz, 380 VAC - 50/60 Hz, 12 VDC, 24 VDC, 27 VDC, 48 VDC.
Connectors in series 9150, normalized DIN 43650, to wire, with IP65 protection rating. Connectors in series 9900, again normalized DIN 43650, pre-wired with various cable lengths, with IP65 protection rating. Connectors in series 9155, to wire, with IP65/68 protection rating.

The "SMART CONNECTOR" systems series 9910 are formed by coupling a connector in series 9152, equipped with an integrated electronic circuit in the connector, with a specific series 9300 coil designed for the connector. These systems have been designed by Castel to be installed on solenoid expansion valves and they allow for:
- a reduction in energy consumption when fully operational with consequent reduction in operating temperature
- an extension of the coil life
- an increase in the MOPD value of the valve
IP65 protection rating. Available voltages; 24 VAC - 50/60 Hz, 220/230 VAC - 50/60 Hz, 240 VAC - 50/60 Hz, 12 VDC, 24 VDC.

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.
