Tokio Keiki DG20V-3-2C-10 Directional Control Valve
The DG20V-3-2C-10 is a high-pressure, solenoid-operated directional control valve developed by Tokio Keiki. This valve is part of the high-performance DG20V series, designed to provide superior reliability in hydraulic systems requiring precise flow direction management. It features a wet-armature solenoid design, which ensures smooth switching, reduced mechanical wear, and quiet operation by immersing the moving parts in hydraulic oil.

Key Features for Industrial Applications
Enhanced High-Pressure Performance
The DG20V series is a significant upgrade in pressure handling, allowing for system pressures up to 30 MPa. This makes the DG20V-3-2C-10 suitable for modern, high-power density hydraulic circuits where standard 21 MPa valves are insufficient.
Wet-Solenoid Reliability
The solenoids used in the DG20V-3-2C-10 are of the wet-armature type. This design eliminates the need for dynamic seals on the push pin, significantly reducing the risk of external leaks and ensuring a long service life even in dusty or harsh industrial environments.
