Product Overview
The NACHI SS-G01-C5-FR-E2-31 is a solenoid operated directional control valve from the NACHI SS series, engineered for precise control of hydraulic fluid flow direction in industrial power units. This valve utilizes a wet-armature solenoid design that shifts a precision-ground spool within a hardened valve body, directing flow between ports to extend, retract, or hold hydraulic actuators. As a standard directional control valve, it serves as a critical interface between the hydraulic power source and the machine’s actuation circuit, providing reliable switching, holding, and directional control functions in demanding industrial environments.
