TOKYO KEIKI TOKIMEC DG4V-3-0C-M-P2-T-7-56 Solenoid Directional Valve
The TOKYO KEIKI TOKIMEC DG4V-3-0C-M-P2-T-7-56 is a legacy three-position hydraulic directional control valve with an open-center No. 0 spool, dual 100 VAC solenoids and an ISO 4401-03 mounting interface.
Open-Center Function
In the spring-centered neutral position, the P, A, B and T ports are interconnected. This unloads the pump and allows the actuator circuit to float when neither solenoid is energized.
Energizing either solenoid shifts the spool to establish the corresponding working flow path. Removing power allows the springs to return the spool to center.

Application Notes
- Confirm that an open-center neutral condition is suitable for the hydraulic circuit.
- Use a 100 VAC solenoid power supply.
- Do not energize both solenoids simultaneously.
- The indicator lamp confirms the electrical command but not the actual spool position.
- Maximum flow depends on operating pressure and the active flow path.
Legacy Model and Replacement Notes
This Design 56 model should be listed for legacy stock, repair or replacement inquiry. Availability and product condition must be confirmed before shipment.
A closed-center or 6C valve is not a functional substitute for this open-center 0C valve. Always verify the hydraulic symbol, voltage, connector and mounting interface.
