TOKYO KEIKI TOKIMEC DG4V-5-7C-M-PL-T-6-40 Solenoid Directional Valve
The TOKYO KEIKI TOKIMEC DG4V-5-7C-M-PL-T-6-40 is a legacy three-position hydraulic directional valve featuring a spring-centered No. 7 spool, two AC solenoids and an ISO 4401-AC-05-4-A mounting interface.
Center and Switching Functions
In the spring-centered neutral position, the P, A and B ports are connected while the T port is blocked. This center function is different from closed-center, open-center, 6C and tandem-center configurations.
Energizing either solenoid shifts the spool to its corresponding working position. Removing both electrical commands allows the centering springs to return the spool to neutral.

Operating Notes
- Confirm the AC supply voltage and frequency before energizing the valve.
- Do not energize both solenoids simultaneously.
- The indicator lamps confirm electrical commands but not physical spool movement.
- Maximum flow must be checked against operating pressure and the active flow path.
- Protect the T port from surge pressure above the specified AC-solenoid limit.
Legacy Model and Replacement Notes
This Design 40 valve should be listed as a legacy stock or replacement-inquiry product. Confirm the product condition, complete nameplate and availability before accepting an order.
A 2C, 6C, 8C or other center configuration is not a functional substitute for this 7C valve. Verify the hydraulic symbol as well as the voltage and electrical connection when selecting a replacement.
