The RPEA3 directional control valves consist of housing
(1), a control spool (5) with two centering springs (4),
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 voltage through the
Ports on the wirebox optional on both sides or through
Connector Item (5 - Pin) M12, see wiring diagram (page
6). 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
(362,5 PSI).
The valve housing (1) is phosphate coated and the
solenoids (2, 3) are zinc coated.

Note: Contrary to the European Norm, the US Standard ANSI-B93.9 states that the solenoid routing on energizing the oil
flow to port A be marked with a, and the solenoid routing on energizing the oil flow to port B be marked with b. This rule
is valid independently from the solenoid lay-out.
