Tokio Keiki DG4V-5-2A-M-P7-H-7-10 Solenoid Valve
The DG4V-5-2A-M-P7-H-7-10 is a high-performance, solenoid-operated directional control valve manufactured by Tokio Keiki (formerly Tokimec). This wet-armature type valve is designed for gasket mounting according to the ISO 4401-05 (Cetop 5) interface. The «2A» configuration identifies it as a two-position, single-solenoid valve with a spring-offset arrangement, making it ideal for applications requiring a default safety position when de-energized. Part of the 10-series design, it is engineered for heavy-duty industrial environments that demand high reliability and quiet switching.

Key Features for Industrial Applications
Reliable 2-Position Spring Offset
The «2A» spool arrangement ensures that the valve remains in its offset position via spring force whenever the solenoid is not powered. This provides a predictable fail-safe state for hydraulic actuators, essential for protecting equipment and personnel in the event of an electrical failure or emergency stop.
High-Pressure «H» Capability
With the «H» high-pressure designation, this valve is capable of handling system pressures up to 31.5 MPa. The wet-armature design immerses the solenoid’s moving parts in hydraulic oil, which provides natural lubrication and cooling. This leads to significantly lower switching noise and a much longer service life compared to traditional dry-solenoid valves.
