RE 29061/10.05
Function, section
The 4/2 and 4/3 proportional directional valves are direct
operated components of subplate mounting design. They are
operated by proportional solenoids with central thread and
removalbe coil. The solenoids are optionally controlled by either
external electronics (type 4WRE) or by the integrated
electronics (type 4WREE).
Design:
Function:
– 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) between the spring plates (X1 and X2)
– 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
The valve basically consists of:
– Housing (1) with mounting face
→ Connection from P to A and B to T via orifice-like crosssections with progressive flow characteristics
– Control spool (2) with compression springs (3 and 4) and
spring plates (X1 and X2)
– De-energising of solenoids (6)
– Solenoids (5 and 6) and pole tubes (P1 and P2) with central
thread
– Position transducer (7)
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.
– Optional integrated control electronics (8)
– The mechanical zero point adjustment (9) is accessible via
the Pg13.5 and the electrical zero point is accessible via the
Pg7 (10) (type 4WREE)

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

Draining of the tank line is to be prevented. Taking the

fitted (back pressure approx. 2 bar).

The cleanliness class stated for the components must be
adhered too in hydraulic systems. Effective filtration prevents
faults from occurring and at the same time increases the
component service life.

A negative command value 0 to –10 V (or 12 to 4 mA) at D and the reference potential at E results in a flow
from P to B and A to T.
For a valve with 1 solenoid on side a (e.g. spool variants EA and WA) a positive command value 0 to +10 V
(or 4 to 20 mA) at D and the reference potential at E results in a flow from P to B and A to T.
Actual value:
Actual value 0 to +10 V resp. 12 to 20 mA at F and the reference potential at C results in flow from P to A
and B to T, 0 to –10 V resp. 4 to 12 mA results in flow from P to B and A to T.
For a valve with 1 solenoid results 4 to 20 mA at F and the reference potential at C results in flow from P to A
and B to T.
