TOKYO KEIKI TOKIMEC DG4V-3-2A-M-P7-H-7-56 Solenoid Directional Control Valve
The TOKYO KEIKI TOKIMEC DG4V-3-2A-M-P7-H-7-56 is an ISO 4401-03 wet-armature hydraulic directional valve featuring a two-position spring-offset configuration, one 24 VDC solenoid and a plug-in electrical connection.
Valve Configuration
The 2A designation identifies a No. 2 spool combined with a spring-offset A arrangement. The valve is shifted electrically in one direction and returned to its default position by spring force when the solenoid is de-energized.
The P7 electrical arrangement provides a plug-in solenoid and conduit box together with an indicator lamp and surge suppressor. This configuration is intended for 24 VDC industrial control systems.

Installation Notes
- Confirm a stable 24 VDC power supply before energizing the solenoid.
- The indicator lamp provides a visual indication of the electrical command.
- The surge suppressor helps reduce switching-voltage transients.
- Maximum allowable flow changes with operating pressure and hydraulic routing.
- Keep the tank line free from abnormal back-pressure surges.
Ordering and Replacement Notes
Confirm the full P7-H-7-56 suffix. A P2-T version uses a different voltage and electrical accessory arrangement and is not electrically interchangeable.
Design 56 is a legacy configuration. When replacing it with a newer DG4V-3 valve, verify the spool symbol, energized flow direction, connector style, coil voltage and allowable tank-port pressure.
