Solenoid Operated Directional
Control Valves with Wirebox
RPEW4-10
The RPEW4 directional control valves consist of housing
(1), a control spool (5) with two centering springs (4) and
cylindrical operating solenoids (2, 3), electric wirebox (9)
and connector (6).
The three-position directional control valves are fitted
with two solenoids and two springs. Two-position
directional control valves have either one solenoid and
one return spring or two solenoids and a detent
assembly.
The solenoids are supplied with DC and AC - voltage
through the 1/2 NPT Ports on the wirebox (optional
on both sides) or through Connector Item (3 - Pin single
solenoid, 5 - Pin - double solenoid) see wiring diagram
(page 7). The wires are connected to a terminal plate
inside the wirebox. Optional lights are installed on this
terminal plate for shift indication. The lights are visible as
raised arrows on the valve label. The solenoids are
retained by the Nut (7) and plug-in to the wirebox. Plug
-in design allows easy removal without wire change.
In the case of solenoid malfunction or power failure,
the spool of the valve can be shifted by manual override
(8), provided the pressure in T- port does not exceed
25 bar (363 PSI).
The valve housing (1) is phosphate coated and the
solenoids (2, 3) are zinc coated.

Operating limits for maximum hydraulic power transferred by the directional valve. For respective spool type - see spool
symbols.The power curves hold true for symmetrical valve flows (e.g. flows in directions P-A and B-T are identical). In case
of an asymmetric flow, the power curves can lie substantially lower. In such cases we highly recommend to consult the
respective power curve with the valve manufacture.

In the case of directional control valves with two solenoids, any of the solenoids may be energized, but only after
powering off the other.
For directional control valves with other spool symbols as those shown in the table, please consult with the
manufacturer.
Other spool symbols on request.
The plastic packaging is recyclable.
The protective plate can be returned to manufacturer.
Mounting bolts, studs and DIN-connectors must be ordered separately.
Certified documentation is available per request.
