The Atos HG-031/210 and HG-031/100 are high-performance modular (stack-type) hydraulic pressure reducing valves engineered for reliable fluid power control. Manufactured in Italy, these pilot-operated valves feature an adjustable spring setting for precise and stable pressure regulation within hydraulic circuits. They are designed with a standard subplate mounting face that includes A, P, T, and B ports, along with four mounting holes for seamless integration into existing manifolds. The “/100” and “/210” designations indicate their respective maximum pressure setting ranges of 100 bar and 210 bar, making them highly versatile for a wide array of demanding industrial hydraulic applications.
