Tokio Keiki DG4V-5-2C-M-P7-H-7-10 Directional Valve
The DG4V-5-2C-M-P7-H-7-10 is a premium, solenoid-operated directional control valve produced by Tokio Keiki. Designed for the ISO 4401-05 (Size 05) mounting interface, this valve is a cornerstone for industrial systems requiring high flow and high-pressure capabilities. The «2C» designation indicates a three-position, spring-centered configuration, allowing for versatile control over hydraulic actuators. This 10-series valve is engineered to provide smooth shifting and long-term durability in the most demanding manufacturing environments.

Key Features for Industrial Applications
Versatile 3-Position Control (2C)
The 2C spool configuration is designed for maximum system stability. In the centered (neutral) position, all ports (P, T, A, and B) are blocked. This ensures that the actuator is held firmly in place and the pump flow is maintained at the valve, allowing for precise positioning and preventing unintended movement in high-load applications.
High-Pressure «H» Engineering
Built for systems operating up to 31.5 MPa, the «H» specification ensures that the valve body and internal components are reinforced for high-stress cycles. The wet-armature solenoid design uses the system’s hydraulic oil to dissipate heat and lubricate the plunger, resulting in exceptionally quiet operation and a significant reduction in mechanical wear.
