Principles of operation, cross section
The sandwich plate design directional valve elements
L511… are compact direct operated solenoid valves
which control the start, the stop and the direction
of the oil flow. These elements basically consist of a
stackable housing (1) with a control spool (2), one or
two solenoids (5), and one or two return springs (4).
When energized, the force of the solenoid (5) pushes
the control spool (2) from its neutral-central position
“0” to the required end position “a” or “b”, and the
required flow from P to A (with B to T), or P to B (with
A to T) is achieved. Once the solenoid is de-energized,
the return spring (4) pushes the spool thrust washer
(3) back against the housing and the spool returns in
its neutral-central position.
Each coil is fastened to the solenoid tube by a ring nut
(6). A pin (7) allows to push the spool (2) in emergency
conditions, when the solenoid cannot be energized, like
in case of voltage shortage.
