Product Description
Atos RZMA Series Modular Proportional Relief Valves
Product Overview: The Atos RZMA Series is a range of high-performance modular proportional relief valves, compliant with ISO 4401 (Size 06) standards. This series is engineered for the continuous and precise regulation of hydraulic system pressure via electrical signals. Typically acting as a pilot control element, the RZMA series stacks directly beneath directional valves or other modular components, significantly simplifying piping and minimizing the installation footprint. Its advanced solenoid design ensures minimal hysteresis and superior repeatability, making it a staple in machine tools, injection molding machinery, and automated production lines.
Featured models on this page include the standard RZMA-A-010/180 and the high-pressure spec RZMA-P1-010/250.
Key Technical Advantages:
Modular Stacking Design: Mounts directly onto CETOP 3 (NG6) standard subplates, eliminating complex piping and reducing potential leak points.
High Dynamic Response: Optimized proportional solenoids provide rapid and smooth pressure transitions, ideal for high-frequency operational cycles.
Low Hysteresis & Linearity: Precision-ground spool architecture combined with Atos amplifiers ensures excellent control linearity and accuracy.
Versatile Pressure Ranges: Available in various pressure ratings up to 180 Bar or 250 Bar to suit diverse system requirements.
