Product Overview
The ATOS DLOH-2C-U 21 is a high-performance solenoid-operated directional control valve engineered by Atos, a globally recognized leader in electrohydraulic technology. This valve functions as a 2-way, 2-position (2/2) directional control element, designed to start, stop, and direct hydraulic fluid flow within industrial circuits. The “DLOH” series is specifically engineered for leak-free operation in holding circuits, clamping systems, and safety-related applications where load holding and pressure integrity are critical. The “2C” spool configuration provides a closed-center function, ensuring that in the de-energized position, the flow path is blocked, thereby preventing actuator drift. The “U” designation indicates a specific solenoid and electrical interface standard, while the “21” denotes the design series. This valve is a direct-acting, poppet-type design, offering fast response times and reliable sealing performance, making it an essential component for precise motion control in demanding industrial environments.
