PRODUCT OFFERINGS

PROPORTIONAL CONTROLS

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.

SAFETY SOLENOID VALVES

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.

CATALOGUE

ELECTRONICS

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.

CATALOGUE

PRESSURE FLOW & CHECK VALVES

Pressure controls include screw-in, sub-plate, in line and SAW flange mounting. Check valves are available as direct operated or pilot operated models.

CATALOGUE

CARTRIDGE VALVES

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.
