Product Overview
The ATOS DLKZOR-TES-SN-NP-140-071/IQ 51 is a high-performance proportional directional valve engineered by Atos (Atos Group), a globally recognized manufacturer of electrohydraulic components. This valve operates on a precise electro-proportional actuation principle, where a proportional solenoid drives a precision-machined spool within the valve body to modulate flow direction and magnitude in direct proportion to the electrical input signal. Unlike simple on/off directional valves, the DLKZOR series provides infinitely variable control of flow rate and direction, enabling smooth acceleration and deceleration of actuators in demanding industrial motion-control systems. The “TES” designation indicates integrated electronic signal conditioning with factory-set and field-adjustable parameters, while the “IQ” suffix denotes advanced digital intelligence features for enhanced diagnostic and control capabilities. This valve serves as a critical interface between electronic control systems and hydraulic power circuits, delivering metered flow for precise velocity and position control of cylinders and motors.
