Product Overview
The ATOS RZGO-A-033/210 31 / E-MI-AC-01F/RR 22 /2 is a high-performance proportional pressure relief valve manufactured by ATOS, a global leader in electrohydraulic control technology. This valve operates on a two-stage, piloted relief principle in which a proportional solenoid (E-MI-AC-01F/RR 22 /2) acts on the pilot stage to infinitely modulate the pressure setting in proportion to the electrical reference signal. The RZGO series is engineered for precise, closed-loop pressure control in demanding industrial hydraulic circuits, delivering smooth, stepless pressure regulation with minimal hysteresis and excellent repeatability. The RZGO-A-033/210 31 designation indicates a size 033 (NG10 / CETOP 5 interface) valve with a maximum adjustable pressure of 210 bar, making it an ideal solution for systems requiring accurate pressure limiting, load holding, or pressure-controlled sequencing.
