These 4/3 directional high-response valves are direct operated
components of sandwich plate design. They are actuated by
control solenoids. The solenoids are controlled by integrated
control electronics (OBE).
Structure:
The valve basically consists of:
– Housing (1) with connection face
– Control spool (2) with compression springs (3 and 4)
– Solenoids (5 and 6)
– Position transducer (7)
– Integrated control electronics (OBE) (8)
– Zero point adjustment (9) accessible via Pg9 cover
Functional description:
– When solenoids (5 and 6) are de-energised, control spool
(2) is held by compression springs (3 and 4) in the central
position
– Direct operation of control spool (2) through energisation of
the control solenoid
e.g. controlling of solenoid "b" (6)
• Control spool (2) is pushed to the left in proportion
to the electrical input signal
• Connection open from P → A and B → T via
orifice-like cross-sections with linear
flow characteristics
– De-energisation of solenoid (6)
Control spool (2) is returned by compression spring (3) to
the central position
In the de-energised state, control spool (2) is held by the return
springs of the solenoid at a mechanical central position. With
spool symbols “V” and “Q”, this does not correspond to the hy-
draulic central position !
When the electrical valve control loop is closed, control spool
(2) is positioned at the hy drau lic central position.
