Product Description

ATOS HR-012 50 Stacking valve

The ATOS HR-012 is a high-performance, direct-acting pressure relief valve designed for modular stacking systems. It conforms to the ISO 4401 size 06 (CETOP 03) standard, allowing for easy integration into compact hydraulic circuits without additional piping. This valve provides precise and reliable control of the maximum pressure in a hydraulic line by diverting excess flow to the tank. Its robust construction ensures long service life and consistent performance in demanding industrial applications. The HR-012 is ideal for limiting pressure in specific branches of a circuit or for protecting the entire system from overpressure conditions.
