Product Overview
The Atos DKZOR-A/B-NP-171-L5 is a high-performance proportional directional valve designed for precise control of flow direction and magnitude in industrial hydraulic systems. Manufactured by Atos, a global leader in electrohydraulic components, this valve features a four-way, three-position spool configuration with direct-operated proportional solenoids. The DKZOR series is engineered to deliver smooth, infinitely variable control of actuator speed and direction, making it ideal for applications requiring accurate motion control, load holding, or synchronized movement. The “NP” designation indicates a normally closed center spool (closed center in neutral), while the “L5” suffix denotes a specific solenoid voltage and connector type (typically 24V DC with a standard DIN connector). This valve is a direct fit replacement for OEM systems and is widely used in plastic injection molding, metallurgical presses, and other demanding industrial machinery.
