Product Overview
The Atos RZMO-A-030/210 40 is a high-performance, direct-operated proportional pressure relief valve designed for precise electronic control of system pressure in industrial hydraulic circuits. Part of the Atos RZMO series, this valve features a robust solenoid actuator that modulates the poppet position proportionally to the input current, enabling stepless pressure regulation from minimal cracking pressure up to the 210 bar maximum setting. The “030” size designation indicates a nominal flow capacity of 30 l/min, while the “40” suffix denotes the specific solenoid and electrical configuration. This valve serves as a critical interface between electronic control systems and hydraulic power, offering fast response, low hysteresis, and excellent repeatability for demanding closed-loop pressure control applications.
