Solenoid operated directional valve rexroth type of 4WE 4 **61/D24 L S

Specifications

Rexroth type solenoid operated directional control valve of 4WE4**61/D24 L S

APPLICATION

Directional spool valves type WE4… electrically operated are intended for change in direction of fluid flow in a hydraulic system and thus it allows to change direction of movement of a receiver - mostly piston rod of a cylinder or hydraulic motor as well to use functions: on and off. These directional spool valves are used for subplate mounting in any position in a hydraulic system.

Directional spool valve is complied with the regulations of directive 2006/95/WE for the following
voltages:
•50 – 250 V for AC
•75 – 250 V for DC

DESCRIPTION OF OPERATION

Main elements of directional spool valve type WE10…
are: housing (1), solenoids (3), control spool (2),
centering springs (4) and manual overrides (5).
The spool (2) is shifted when it is moved into one of
end positions by the force of solenoid (3) affecting it.
The return of the spool into neutral position and
centering are secured by the centering springs (4).
The shape of the spool (control edge spacing) affects
the configuration of connections among the ports: A,
B, P and T.
In case of emergency, the spool can be shifted
manually by means of the override (5) – only for
version with manual override. 

When the situation is anticipated, directional spool valve
must be mounted in the way as to be available.
WE10…-12/OF…- only for spools: A, C, D.
Two-position directional spool valve
without return springs with detent. The
spool (2) is positioned and supported with
detent (6), and its shift results from
supplying voltage to one solenoid (3).
