Purchase now: Tokyo Keiki DG4V-5-7C Solenoid Valve
Purchase now: Atlantech Drives provides you the Tokyo Keiki DG4V-5-7C-U-H-100 (Tokimec), a high-flow **Solenoid Operated Directional Control Valve**. Designed according to the **ISO 4401-05 (CETOP 5 / NG10)** mounting standard, this valve is engineered to handle higher flow rates (up to 120 L/min) compared to the smaller DG4V-3 series. It is a direct-acting valve used to control the start, stop, and direction of fluid flow in hydraulic cylinders and motors.
Technical Specifications and Spool Logic
The DG4V-5 series features a robust «Wet Armature» solenoid design for long life and quiet operation. The **»7C»** code refers to the spool type: it is **Spring Centered** (returns to neutral when de-energized). While Type 2 (All Blocked) and Type 6 (Motor Float) are common, Type 7 spools typically provide specific center conditions (often P to A&B or similar specific paths – please verify circuit diagram). The **»H»** suffix denotes an electrical conduit box connection, allowing for secure terminal wiring in harsh environments.

Expert Installation Advice: Mounting Bolts
Upgrading from CETOP 3 to CETOP 5? Expert Tip: The DG4V-5 handles significantly more force. Use High Tensile (Class 12.9) mounting bolts. Standard 8.8 bolts may stretch under the 315 Bar pressure load on the larger NG10 footprint, causing O-ring extrusion and leakage between the valve and the manifold. Torque them to the specified 12-15 Nm (check manual) in a crisscross pattern.
Frequently Asked Questions (FAQs)
Q: Can I replace a Vickers DG4V-5 with this?
A: Yes, Tokyo Keiki (Tokimec) was a licensee of Vickers, so the footprint and function are directly interchangeable.
Q: What voltage is the coil?
A: The code provided doesn’t explicitly state the voltage (e.g., P7 or P2). Check the nameplate on the solenoid housing. «H» usually refers to the box type, not the voltage.
