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.
