Purchase now: Tokyo Keiki DG4V-3-6C Solenoid Valve
Purchase now: Atlantech Drives provides you the Tokyo Keiki DG4V-3-6C-M-P7-H-7-P22-54 (Tokimec), a premium **Solenoid Operated Directional Control Valve**. This valve conforms to the **ISO 4401-03 (CETOP 3 / NG6)** mounting standard, making it a versatile replacement for global standard valves. Known for its «Wet Armature» design, it offers superior life expectancy, low switching noise, and zero external leakage, making it a staple in high-precision machine tools.
Technical Specifications and Spool Type
The **»DG4V-3″** series handles pressures up to 35 MPa. The **»6C»** code indicates a **Spring Centered, Type 6 Spool**. In the center (neutral) position, the Pressure port (P) is blocked, while the A and B work ports are connected to the Tank (T). This is commonly used in motor applications to allow the motor to freewheel (float) when stopped, or for cylinders requiring external force positioning. The **»P7″** coil is rated for **200 V AC**, and the valve includes an electrical conduit box with indicator lights.

Expert Tips: Solenoid Burnout Prevention
AC solenoids are powerful but sensitive. Expert Tip: Unlike DC coils, AC coils have a high «inrush current». If the spool sticks due to oil contamination and cannot fully shift, the coil will draw high current continuously and burn out in seconds. If you experience frequent coil failures on P7 valves, check your oil cleanliness or consider upgrading to a DC coil valve with a rectifier (which Tokyo Keiki also offers) for more robust operation.
Frequently Asked Questions (FAQs)
Q: What is the «P22» in the code?
A: This often refers to a back-pressure rating or a specific internal orifice option to dampen the spool shift, reducing hydraulic shock (water hammer) in the system.
Q: Is it compatible with Vickers DG4V-3-6C?
A: Yes, Tokyo Keiki was formerly a licensee of Vickers (Tokimec), so the model codes and mounting interfaces are virtually identical.
