APPLICATION
nnnnDirectional spool valves type WE6... electrically
nnnnoperated are intended for change in direction of fluid
nnnnHow in a hydraulic system and thus it allows to
nnnnchange direction of movement of a receiver - mostly
nnnnpiston rod of a cylinder or hydraulic motor as well to
nnnnuse functions: on and off. These directional spool
nnnnvalves are used for subplate mounting in any position
nnnnin a hydraulic system.
nnnnDirectional spool valve is complied with the
nnnnregulations of directive 2006/95/WE for the following
nnnnvoltages:
nnnn•50-250 V for AC
nnnn•75-250 V for DC
nnnnDESCRIPTION OF OPERATION
nnnnA WE 6J-12/G42NZ4
nnnnMain elements of directional spool valve type WE6...
nnnnare: housing (1), solenoids (3), control spool (2),
nnnncentering springs (A) and manual overrides (5).
nnnnThe spool (2) is shifted when it is moved into one of
nnnnend positions by the force of solenoid (3) affecting it.
nnnnThe return of the spool into neutral position and
nnnncentering are secured by the centering springs (A).
nnnnThe shape of the spool (control edge spacing) affects
nnnnthe configuration of connections among the ports: A,
nnnnB, PandT.
nnnnIn case of emergency, the spool can be shifted
nnnnmanually by means of the override (5) - only for
nnnnversion with manual override.
nnnnWhen the situation is anticipated, directional spool valve
nnnnmust be mounted in the way as to be available.
nnnnWE6...-12/OF...-only for spools: A, C, D.
nnnn2-position directional spool valve without
nnnnreturn springs with detent. The spool (2) is
nnnnpositioned and supported with detent (6),
nnnnand its shift results from supplying voltage
nnnnto one solenoid (3).
