Eaton VICKERS SystemStak User Manual

2 EATON Vickers Solenoid Operated Directional Valves Product Catalog V-VLDI-MC011-E September 2008
• Surge supression for
DC valves
Surge suppression is used
to prevent coil damage by
reducing contact burnoff –
increasing switch life – and
protecting electrical control-
lers from inductive spikes.
Three coil options are
available:
D1 – Encapsulated diode
(Industrial application)
D2 – Encapsulated diode
(Mobile application)
D7 – Transzorb type
Features and
Benefits
• Minimal pressure drop,
i.e. 2,5 bar (36 psi) at
30 l/min (7.9 USgpm)
Achieved by optimization of
the valve body, spool and
spool-stroke design. The
results: low energy consump-
tion and improved efficiency.
• High reliability
Design of spring forces and
profile of DC solenoid force
characteristics ensure spool
position selection under
extreme operating condi-
tions. Result is a valve with
high reliability when being
energized or de-energied.
• Scratch-proof manual
override seal
Internal seals are located
such that they are beyond
reach of any bore damage
caused by small tools used to
operate the manual override.
Result is no messy oil drips
from the manual overrides.
Small diameter manual over-
rides prevent inadvertent
operation.
• Ease of servicing
Wet-armature solenoid,
screw-in core tube design
allows coils to be changed
without removing valve from
installation and without oil
spillage or risk of contaminat-
ing system fluid.
• Electrical connections
Conduit box design that
simplifies electrical wiring
connections to solenoids.
Orientation tabs prevent
incorrect positioning.
