OVERVIEW

P104 435E

DCV 03 directional control valves consist of: housing (1), control spool (5), with two
centering springs (4), and cylindrical operating solenoids (2, 3).
The three-position directional valves have two solenoids and two springs. Two-position
directional valves have either one solenoid and one return spring or two solenoids and a
detent assembly.
The operating solenoids are DC. For AC supply the solenoids are provided with a rectifier,
which is integrated directly into the coil.
The plug connectors (6, 7) can be rotated 90°. By loosening the nut (8), the solenoids can
be rotated 360°. This enables the solenoids to be replaced without opening the valves.
In the case of solenoid malfunction or power failure, the spool can be actuated by
manual override (9), provided the pressure in T-port does not exceed 25 bar [360 psi].
The valve housing (1) is phosphate coated. The operating solenoids (2, 3) are zinc coated.
