A pioneer in electrohydraulics, Atos offers one of the most advanced lines of proportional valves enabling similar or better performances in comparison with servo valves. Atos proportional valves maintain typical benefits of proportional electrohydraulics: less sensitivity, coarser filtration requirements, intrinsic stability, easier servicing and lower cost.
Atos is a leading international manufacturer of high quality hydraulic solenoid valves, offering a complete line of various sizes and versions
  • sealed and rugged execution by ECP protection, suitable for outdoor use.
  • wide choice of coils and electric-electronic connectors.
  • safety devices by micro switches or inductive proximities TÜV certified.
  • full line of versions: switching control devices, explosion-proof, military, stainless steel, zero leakage, intrinsically safe.
A range of ISO modular valves, engineered design, to be packed below ISO solenoid valves
  • Flow to 300 l/min
  • Pressure to 350 bar
Explosion-proof valves, on-off or proportional, for use in potential explosive environments for presence of gas or flammable dust. Solenoids are of original design, integral and consistent to the valves.
Tested and certified to following standards
  • Multicertification ATEX, IECEx, EAC
  • Group I Gas – Mining
  • Group II Gas and dust
  • US & Canadian standards
  • UL429, UI1203 and CSA 22.2
  • PESO Certification by Government of India
  • MA Chinese Mining Certification
Atos offers a full line of electrohydraulic controls in stainless steel for corrosive environments and special fluids. This rugged inoxidizable design is suitable for use with mineral oils, water glycol as well as special hydraulic fluids. SS Valves are also available in special execution for water hydraulics applications. Original stainless steel; solenoids are explosion proof type, with possible ATEX or UL ex-proof certification.
Safety valves are specifically designed to ensure protection; they are equipped with specific devices for monitoring spool position and the relevant hydraulic status. The valves operate by cutting the line of hydraulic power to an actuator in case of emergency processes or safety conditions.
Atos electronics includes analog and digital drivers for proportional components plus digital controllers to manage the closed-loop control of position, speed and/or force. Electronic drivers and digital axis controls may be integrated on proportional valves. Integral electronics, factory preset, ensures optimal functionality plus valve-to-valve interchangeability and simplification of installation wiring and system set-up.
Pressure controls include screw-in, sub-plate, in line and SAW flange mounting. Check valves are available as direct operated or pilot operated models.
A full line of cartridge valves composed by a poppet or spool cartridge and by a functional cover that retains the ISO cartridge into properly machined blocks and provides hydraulic piloting. Cartridge valves are offered in on-off or proportional function according to the modular composition of functional covers.
Axial piston pumps - PVPC pumps are variable displacement axial piston pumps for high pressure operation with low noise level and long service life.
Vane pumps - PFE fixed displacement vane pumps are high-performance industrial pumps offering remarkable features including excellent reliability, long working life, over 106 cycles, low noise level, suitable for hydraulic oils or synthetic fluids. ATEX verified execution is available upon request.
