D05 Single Solenoid Operated Directional Valve – DIN Coil Type, 2 Position Spring Offset – P to A, B to T (Closed in Transition) – 12VDC – D05SD-1A-12D-35

The Hyvair D05SD-1A-12D-35 is a single solenoid, 2-position, spring offset directional valve for the NFPA T3.5.1.MR1-D05 / ISO 4401-05 mounting interface. It belongs to the D05 Series 35 and uses spool code 1A, which gives a P to A, B to T flow path. The spool is closed in transition, so ports stay blocked while the spool moves between positions.

The valve is rated for 5000 psi maximum operating pressure and 34.1 gpm maximum flow. The tank port is rated to 2320 psi, so check return line back pressure when the valve shares a tank line with other functions.

The coil is a 12 VDC DIN coil with a 3-pin DIN 43650 Form A / ISO 4400 electrical connection. It operates within a permissible voltage range of 10.8 to 13.2 V and has a holding power of 31 W. Indicator lights are available as an option on the connector. A push pin manual override lets you shift the spool by hand during setup or troubleshooting.

For best service life, run the valve on oil filtered to 25 micron or finer, with fluid temperature between 41°F and 140°F and viscosity between 80 and 1400 SUS. A bolt kit with four 1/4-20 socket head cap screws, 1-1/2 in long, is included for mounting.
