RE 29 061/12.98
061/03.98

Function, section
The 4/2 and 4/3 proportional directional valves are directly controlled
components of subplate mounting design. They are operated by proportional solenoids with central thread and removable coil. The solenoids are optionally controlled by either external control electronics
(type WRE) or by integrated control electronics (type WREE).
Design:
The valve basically consists of:
Housing (1) with mounting face
Control spool (2) with compression springs (3 and 4)
Solenoids (5 and 6) with central thread
Position transducer (7)
Optional integrated control electronics (8)
The mechanical zero point adjustment (9) is accessible via the
Pg 13.5 and the electrical zero point is accessible via the Pg 7 (10)
(type 4WREE)

Functional description:
With the solenoids (5 and 6), de-energised, the control spool (2)
is held in the central position by the compression springs
(3 and 4)
Direct operation of the control spool (2) by energising one of the
proportional solenoids, e.g. control of solenoid "b" (6)
Movement of the control spool (2) to the left in proportion
to the electrical input signal
Connection from P to A and B to T via orifice like cross-sections
with progressive flow characteristics
De-energising of solenoid (6)
The control spool (2) is returned to the central position via the
compression spring (3)
In the de-energised condition the spool (2) is held in a mechanical centre
position by the solenoid return springs. This, for the spool symbol "V",
does not relate to the hydraulic centre position! When the electrical valve
closed loop control circuit is closed then the spool is positioned in the
hydraulic centre position.

Valve with 2 switching positions: (type 4WREA)
The function of this valve version is basically the same as that of the
valve with 3 switching positions. The 2 switching position valves are
however, only fitted with solenoid "a" (5). A plug (11) is fitted
in place on the 2nd proportional solenoid.

Note for type 4WRE-2X/G24:

Draining of the tank line is to be prevented. Taking the installation
conditions into account a back pressure valve is to be fitted (back
pressure approx. 2 bar).
