The TOKYO KEIKI TOKIMEC DG4V-3-2A-M-P7-H-7-52 is a legacy Design 52 wet-armature hydraulic directional control valve with a two-position spring-offset spool, one 24 VDC solenoid and an ISO 4401-03 mounting interface.
The 2A designation combines a No. 2 spool with a spring-offset A arrangement. The valve is electrically shifted by one solenoid and mechanically returned by spring force after the electrical command is removed.
The P7 connection includes a plug-in solenoid, conduit box, indicator lamp and surge suppressor. This arrangement is designed for 24 VDC machine-control circuits.

Design 52 is an older, discontinued configuration and should be offered on an availability, repair or replacement-inquiry basis. Do not describe it as a current factory-production model without supplier confirmation.
A later Design 56 or Design 100 valve may be considered only after confirming the complete hydraulic symbol, energized flow direction, voltage, electrical connector and allowable tank-port pressure.
