Atos
Atos is an Italian specialist in electrohydraulics—the integration of hydraulics with advanced digital electronics—offering one of the industry's broadest lines of proportional, on-off, and cartridge valves alongside pumps, cylinders, and complete electrohydraulic systems.
About Atos
Founded in 1957 and headquartered in Sesto Calende, Italy, Atos has grown into a global electrohydraulics specialist operating in more than 80 countries, with production sites across Italy, China, India, and North America. Atos built its reputation by combining advanced digital electronics with high-performance hydraulic components, pushing proportional valve technology to rival the precision of servo valves while keeping the durability and simplicity hydraulic systems depend on.
The Atos product range spans three main lines—Industrial, Explosion-Proof, and Stainless Steel—covering proportional and on-off directional valves, pressure and flow controls, cartridge valves, hydraulic pumps and servopumps, cylinders and servocylinders, filters, and complete systems and manifolds. Many Atos valves carry IP66/67 ratings and integrate onboard diagnostics, making them a fit for both standard industrial machinery and demanding hazardous-environment applications.
Flow Dynamics and Automation stocks and supplies Atos valves, pumps, and components, and for units that need service, we coordinate factory-authorized repair through Atos.
