TOKYO KEIKI TOKIMEC DG4V-5-2A-M-P7L-H-7-40 Solenoid Directional Valve
The TOKYO KEIKI TOKIMEC DG4V-5-2A-M-P7L-H-7-40 is a legacy wet-armature hydraulic directional valve with a two-position spring-offset No. 2 spool, one 24 VDC solenoid and an ISO 4401-05 mounting interface.
Operating Configuration
The 2A configuration uses a spring-offset A arrangement. In the standard build, energizing the solenoid establishes P-to-B and A-to-T flow. Removing the electrical signal allows the spring to return the spool to its normal position.
The No. 2 spool incorporates a closed-center transition. The P7L electrical arrangement uses a plug-in conduit box and includes an indicator lamp and surge-suppression function for the DC coil.

Installation Notes
- Confirm that the control system supplies 24 VDC.
- The indicator lamp confirms coil current, not physical spool movement.
- Maximum permissible flow varies with pressure and hydraulic routing.
- Keep tank-port back pressure within the specified limit.
- Verify the normal and energized flow directions before installation.
Legacy Model and Replacement Notes
This Design 40 valve is a legacy product. Product condition, manufacturer nameplate, electrical accessories and stock status must be confirmed before shipment.
Later Design 50 valves should not be installed solely on the basis of a similar model code. Check body dimensions, mounting bolts, spool function, voltage and electrical connection.
