Product Overview
The ATOS RZMO-P1-010/100 20 is a pilot-operated proportional pressure relief valve from the Atos RZMO series, designed for electro-proportional control of system pressure in industrial hydraulic circuits. The valve modulates its pressure setting in direct proportion to the electrical reference signal supplied to the integrated proportional solenoid, enabling continuous, stepless pressure regulation rather than fixed-step adjustment. The “010” size designation corresponds to a nominal flow capacity of 10 L/min, while the “100” identifies a maximum adjustable pressure of 100 bar. The “20” suffix denotes the Atos series generation, ensuring dimensional and functional interchangeability with equivalent RZMO valves of the same series. As a normally closed, spring-offset proportional relief valve, the RZMO-P1-010/100 20 limits circuit pressure by diverting excess flow to tank when the electrically commanded setpoint is reached, making it a core pressure-control element in proportional hydraulic systems.

Engineering Features & Advantages
- Precision Proportional Metering: The proportional solenoid and pressure-compensated pilot stage deliver smooth, hysteresis-minimized pressure modulation across the full 0–100 bar range, allowing accurate closed-loop pressure control in dynamic industrial cycles.
- Stable Pressure Regulation: The pilot-operated architecture isolates the main poppet from flow forces, maintaining consistent pressure setpoint accuracy even as system flow varies within the 10 L/min nominal capacity.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened internal components and a robust solenoid coil rated for sustained duty cycles in demanding hydraulic power units.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original ATOS standards, allowing straightforward retrofit into existing hydraulic systems without rework.
Typical Industrial Applications
As a normally closed, spring-offset proportional relief valve, the RZMO-P1-010/100 20 limits circuit pressure by diverting excess flow to tank when the electrically commanded setpoint is reached, making it a core pressure-control element in proportional hydraulic systems.
