DG4V Series vickers hydraulic solenoid valve

Specifications

DG4V Series vickers hydraulic solenoid valve

 Solenoid Energizing
Spring centered and spring offset valves will be spring positioned unless the solenoid is energized continuously.
NOTE
Any sliding spool valve, if held

shifted under pressure for long
periods, may stick and not spring
return, due to silting. Therefore, it is
recommended that the valve be
cycled periodically to prevent this
from occurring.
Only DC coil voltages are available.
For applications where the junction
box is required, valves with F (flying
lead) type coils must be driven by a
DC electrical signal. The P12L
models must be driven by a 110-120,
50-60 Hz AC signal. For other
applications, rectified DIN
connectors (‘11’ or ‘12’ in model
code) can be used to convert AC
input voltage to the DC voltage
necessary to power the valve.

NOTE
The P12L designated coil is rectified.
Bleeding Procedure
Apply a minimum of 3.4 bar (50 psi) tank
pressure. Shift either solenoid “a” or “b”.
Loosen manual actuators in solenoid
ends until air is evacuated. Retighten
manual actuators. No further bleeding
should be required.
Initial start ups thereafter will require 6-8
shifts to refill solenoid tubes. Addition of
a back pressure check valve may be
required to prevent bleed down.
Drain
The tank line must be plumbed above
the level of the core tube (and valve
body). This will insure that the tank port

is always flooded with oil. By doing this,
the core tube will remain flooded with oil
and the soft shift operate as designed.
