Product Overview
The TOKYO KEIKI DG4SM-3-33C-P7-H-56 is a high-performance solenoid-operated directional control valve from the renowned DG4SM series, engineered by Tokyo Keiki (now part of the Nabtesco Group) for precise flow direction control in demanding industrial hydraulic systems. This valve utilizes a robust wet-armature solenoid design with a spring-centered, spring-offset spool configuration, ensuring reliable and repeatable shifting between flow paths. The DG4SM series is widely recognized for its high-pressure capability, low pressure drop, and exceptional spool response characteristics, making it a preferred choice for critical motion control circuits in heavy machinery and automated production equipment. The “P7” designation indicates a specific spool type and flow capacity, while “H-56” denotes the electrical connection and coil rating configuration. This valve serves as a direct-fit replacement for OEM installations and is suitable for both new system designs and maintenance applications.
