Founded in 1957, ATOS, headquartered in Sesto Calende, northern Italy, is a leading integrator of global electro-hydraulic components and systems. With decades of expertise in electro-hydraulic technology and over half a century of experience in producing electro-hydraulic products, ATOS integrates advanced technologies into its hydraulic and electronic products to enhance modern machinery performance. ATOS manufactures over one million components annually, leveraging modern machinery, advanced processing methods, professional production techniques, and an outstanding R&D team to establish itself as an expert in electro-hydraulic technology. Its innovative designs and continuously updated patents have positioned ATOS as one of the world leaders in the industry.

　　ATOS boasts a comprehensive range of hydraulic products, all of which undergo rigorous quality inspections before leaving the factory. The design and manufacturing of ATOS's hydraulic and electronic components fully embody the concept of "modular combination," utilizing a limited number of thoroughly tested parts for assembly. The dimensions and quality of all ATOS components comply with international standards such as ISO, DIN, SAE, and CE safety certification standards.

　　ATOS's advanced technology is evident in component design, product engineering, production methods, quality, and system applications. Hydraulic systems transmit energy and control machine movements through the flow of mineral or synthetic fluids, enabling safe and stable application of immense force and power in any environment. ATOS's electro-hydraulic systems enhance the uniqueness of hydraulic systems, with electronics providing significant control advantages for rapid, smooth, and precise movements.

　　ATOS offers electro-hydraulic and electromechanical products featuring built-in overload protection, automatic force adaptation, self-lubrication, fast operational response, high power density, energy storage capabilities, stepless speed and force variation, long service life, high reliability, and ease of programming. The design and manufacturing of ATOS's hydraulic and electronic components achieve complete consistency through the modular "meccano" concept using a limited number of fully tested components. Most hydraulic components feature a cartridge design, and the modular concept ensures high versatility in system assembly and easy on-site maintenance.

　　ATOS's components meet international standards (ISO, DIN, SAE, etc.) for dimensions and quality assurance, as well as CE safety requirements. Key ATOS products include proportional valves, digital proportional valves, conventional valves, stack valves, vane pumps, piston pumps, cylinders, amplifiers, and controllers.

　　As a leader in advanced electro-hydraulic technology, ATOS now offers an advanced range of proportional valves that offer similar or better performance than servo valves while maintaining the typical advantages of proportional electro-hydraulics, with stricter filtration requirements for cost-effective operation. ATOS's hydraulic cylinders comply with ISO 6020 and 6022 international standards, with peak pressures reaching 350 bar. These cylinders can be equipped with cushioning devices and sensors for detecting piston positions. Additionally, ATOS produces servo-proportional valves with spool-and-sleeve configurations.

　　ATOS's adjustable flow pumps have specifications up to 98 cm³/r and are equipped with corresponding flow electronic controllers. Its radial piston pumps can withstand pressures up to 500 bar, and its vane pumps are available in fixed or adjustable displacement types, compatible with PTOs. The company's pump series is diverse, allowing different types of pumps to be connected as needed. ATOS's solenoid valve systems are structurally simple, facilitating computer connection and offering highly competitive pricing. These valves are characterized by their leak-proof exterior, easy control of internal leaks, and safe usage, especially in corrosive, toxic, or extreme temperature environments.

　　ATOS's digital motion controllers are modern solutions for axis control in machines and systems. They can be programmed using ATOS's intuitive software, managing the position, speed, or force of any electro-hydraulic axis, enhancing motion performance, simplifying automation architectures, and effectively connecting to fieldbuses.

　　Over the years, ATOS's products have gained widespread recognition and acclaim in various industries worldwide. The ATOS brand enjoys a certain reputation in the hydraulic industry, with multiple factories across the globe. ATOS's proportional valves, servo valves, and cylinders are widely used in China's major metallurgical industries. The company's continuous innovation and optimization of products, through regular updates and the introduction of new products, have provided users with better quality and higher efficiency. ATOS adheres to a product philosophy of excellence in quality and meticulous attention to detail, contributing significantly to industrial development with its superior product quality, enthusiastic service, and advanced technology, earning widespread recognition within the industry.
