VICKERS DG5S-H8-0C-EMU-C7-40 / DG4V-3-6C-MU-C7-30

Vickers DG5S H8 Two-Stage Hydraulic Directional Control Valve

Description

This is a used but fully functional two-stage directional control valve from Vickers, a trusted name in hydraulics now part of Eaton. The assembly consists of a DG5S H8 mainstage valve controlled by a DG4V-3 pilot valve. It is designed for high-flow industrial hydraulic applications requiring precise solenoid control. The robust construction ensures long service life even in demanding environments.

FAQ

What type of hydraulic fluid is compatible with this Vickers DG5S H8 valve?

This valve is designed for use with standard petroleum-based hydraulic fluids (HL, HLP). For use with synthetic fluids, water-glycol, or other special fluids, consult the Eaton/Vickers technical datasheet to ensure seal compatibility.

How can I manually operate this valve in case of a power failure?

The solenoids on the DG4V-3 pilot valve are equipped with manual overrides. These are the black knobs/pins at the end of each solenoid. You can push these in with a tool to shift the pilot spool and, consequently, the main stage spool. Always de-pressurize the system before performing maintenance.

What does the ‘OCEM’ in the model code DG5S H8 OCEM signify?

The ‘OCEM’ code refers to the main stage spool type. It specifies an ‘open-center, motor’ spool. In the center position, this spool connects the pressure port (P) to the tank port (T) while also connecting the work ports (A and B) to the tank, which is ideal for applications with fixed displacement pumps or for allowing a hydraulic motor to coast.
