Atos digital proportional directional valves of the DHZO (size 06, ISO 4401-03 / CETOP 3), DKZOR (size 10, ISO 4401-05 / CETOP 5), and pilot-operated DPZO (sizes 10 to 32, ISO 4401 / CETOP 5-10) series deliver high-dynamic, stepless control of fluid flow direction and rate for CNC machine tools, industrial forming presses, plastics injection molding machines, and automated heavy production lines.

Featuring rugged integrated On-Board Electronics (OBE) with standard industrial Fieldbus communication interfaces (CANopen, PROFIBUS DP, EtherCAT, PROFINET, POWERLINK) or analog ±10V / 4-20mA control signals, these valves utilize precision-ground spool and sleeve pairings and high-frequency LVDT spool position feedback transducers to guarantee minimal hysteresis, exceptional linearity, and outstanding motion repeatability under continuous high-pressure industrial operations.

Selection criteria: ISO 4401 mounting size (06, 10, 16, 25, 32), spool profile (L, S, D), electronic interface (analog, CANopen, Profibus, EtherCAT), 24V DC supply.

Atos SDHE, DHI, DKE and DPHE Solenoid Directional Spool Valves

Industrial directional solenoid spool valves from Atos, including direct-operated SDHE and DHI (size 06, ISO 4401-03), DKE (size 10, ISO 4401-05), and two-stage pilot-operated DPHE (sizes 16 to 32), are engineered for reliable start, stop, and direction switching of hydraulic fluid.

Cast from high-grade meehanite iron using shell-molding techniques with fluid-dynamically optimized internal passages, these valves reduce circuit pressure drops by up to 30%.

Wet-pin solenoids with threaded, interchangeable coils enable silent, cushioned spool actuation and rapid field replacement without depressurizing hydraulic circuits.

Selection criteria: ISO mounting interface (06, 10, 16, 25, 32), spool scheme (0, 1, 2, 3, 4, 6), coil voltage (12V/24V DC, 110V/230V AC), DIN 43650 connector.

Atos DLHZO, DLKZOR and DPZO-L High-Response Servoproportional Valves

Atos high-response servoproportional directional valves, comprising direct-operated DLHZO (size 06) and DLKZOR (size 10), alongside pilot-operated DPZO-L (sizes 16 to 32), represent high-performance electrohydraulic control featuring zero-lap spools fitted within precision-honed hardened steel sleeves.

Engineered for closed-loop motion, position, velocity, and force servo-control in hydraulic forming presses, test benches, continuous rolling mills, and CNC machinery, these valves achieve dynamic frequency responses up to 120-160 Hz, ensuring instantaneous response to complex command trajectories.

Selection criteria: nominal flow rate (5 to 1000 l/min), dynamic frequency response, LVDT sensor type, E-RI-TES axis controller configuration.

Atos AGAM, ARAM, ARE Pressure Relief Valves and CETOP Modular Valves

Atos pressure control valves of the pilot-operated AGAM, ARAM, direct-acting ARE, unloading REM, and proportional AGMZO, RZMO, AGMZE series provide dependable overpressure protection, accurate pressure reduction, and stepless remote pressure modulation in demanding industrial circuits.

Complemented by CETOP 03 and CETOP 05 modular sandwich valves (HMP, HM, KM, HR, KR series), they stack vertically beneath directional valves, eliminating external piping interconnections, reducing manifold footprint, and preventing fluid leakage across critical industrial lines.

Selection criteria: pressure range (up to 50, 100, 210, 315, 350 bar), nominal flow (up to 500 l/min), venting logic, CETOP mounting standard.

Atos CK, CH, CN, CC Hydraulic Cylinders and CKS Servocylinders

Atos industrial hydraulic cylinders, including the heavy-duty tie-rod CK series (ISO 6020-2, DIN 24554, 160 bar), high-pressure CH series (250 bar), round flange CN series (ISO 6022), and compact welded CC series, deliver heavy-duty linear actuation across metallurgy, molding, forging, and marine engineering.

Constructed with induction-hardened hard-chrome plated piston rods (minimum 20 um plating), precision-honed seamless barrels, and low-friction polyurethane seals, they ensure extended service life.

High-performance CKS servocylinders integrate non-contact magnetostrictive position transducers and close-coupled servoproportional valves for sub-millimeter positioning precision.

Selection criteria: bore diameter (25 to 200 mm), rod diameter, stroke length (up to 5000 mm), mounting style (clevis, trunnion, flange), seal composition.

Atos PFE, PFED Fixed Vane Pumps and PVPC Variable Axial Piston Pumps

Atos hydraulic pumps, encompassing fixed-displacement vane pumps (PFE single, PFED double tandem) and variable-displacement axial piston pumps (PVPC series), provide robust fluid power for machine tools, forming presses, plastic machinery, and material handling systems.

PFE vane pumps feature a modular cartridge design delivering exceptionally low operating noise (65-72 dBA) and negligible flow pulsation, enabling field serviceability via cartridge replacement in minutes.

Swashplate PVPC piston pumps offer mechanical pressure compensators, Load Sensing (LS) controls, and electrohydraulic proportional displacement modulation.

Selection criteria: displacement (PFE: 16-150 cc/rev, PVPC: 29-90 cc/rev), pressure rating, control type (CZ, CZR, CH, PE), shaft profile (keyed, splined).

Atos Digital Electronic Drivers, Eurocards and Motion Axis Controllers

Atos advanced digital electronic control modules, including E-ME-AC Eurocard (19") format amplifiers, E-BM-AC DIN-rail modules, integrated on-board valve drivers (E-RI-AEB/AES), and dedicated digital axis controllers (E-RI-TES/LES), deliver high-precision regulation of proportional electrohydraulic valves and multi-axis servocylinders.

Real-time Digital Signal Processing (DSP) allows users to fine-tune acceleration/deceleration ramps, linearize spool flow profiles, and compensate deadband non-linearities.

Configuration, parameterization, and oscilloscope diagnostics are performed via the intuitive Atos Z-SW software suite over USB, RS232, or industrial Fieldbuses.

Selection criteria: form factor (DIN rail, Eurocard, OBE), bus protocol (Profibus, CANopen, EtherCAT, Profinet), solenoid channels, SSI transducer inputs.
