Explosion-Proof Hydraulic Valves ATEX Qualified

Aidro ATEX explosion-proof hydraulic valves are engineered for hazardous gaseous and dusty environments found in petrochemical refineries, fuel terminals, chemical processing, and offshore maritime platforms, providing flameproof solenoid coil operation.

Flameproof solenoid coil enclosures meeting thermal classes T5 and T6 standards
Directional on-off valves, proportional flow units, and zero-leak poppet valves
European directive 2014/34/EU compliance for explosive Gas and Dust environments
Corrosion-resistant exterior fasteners and protective chemical surface plating

Additive Manufactured AMES Valves and 3D Manifolds

Aidro patented HD2-AMES and HD3-AMES valves alongside monolithic manifolds are produced via Laser Powder Bed Fusion (LPBF) and Binder Jetting using 316L stainless steel, AlSi10Mg aluminum, and Inconel 718, eliminating cross-drilled passages and auxiliary plugs.

Elimination of internal and external leakage risk by removing auxiliary plugs
Smooth organic internal fluid channels free of sharp 90-degree bend junctions
Manifold mass reduction up to 55 to 60 percent while preserving structural rigor
Proof pressure testing verified up to 700 bar for demanding subsea deployment

Design principles of subplate directional valves conforming to CETOP standards

Modular subplate mounting of directional control valves according to CETOP and ISO 4401 standards delivers high packaging density and rapid maintenance without uncoupling piping connections.

In the Aidro portfolio, spool directional valves in NG04, NG06, and NG10 sizes feature interchangeable solenoid coils for direct and alternating current operation.

Precision finished valve bodies paired with hardened ground spools ensure minimal internal fluid migration under working pressures up to 350 bar.

Accurately contoured metering notches on the spool eliminate hydraulic line shocks during fluid switching, while resilient sealing rings maintain complete external joint integrity.

Screw-in cartridge valve technology and LAB inline connection bodies

Utilizing screw-in cartridge valves enables hydraulic system builders to construct compact integrated manifold assemblies with reduced weight and streamlined dimensions.

Aidro cartridge inserts fit standardized SAE 08 and SAE 10 cavities, providing dependable pressure holding and consistent flow throttling.

For discrete piping installation directly into pressure lines, LAB series inline bodies fabricated from high-strength anodized aluminum or alloy steel provide BSPP fluid ports.

Precision-machined cavity seats eliminate component binding during demanding cyclic duty in heavy industrial manufacturing environments.

Proportional fluid regulation and digital electronic driver modules

Aidro proportional hydraulic components provide continuous modulation of linear velocity and thrust for hydraulic cylinders and rotary motors in automated machinery.

Operating alongside microprocessor driver control units, proportional valves deliver high response linearity and minimized hysteresis throughout the entire adjustment band.

Driver electronics output stabilized coil current with adjustable pulse width modulation frequency, compensating for variations in fluid temperature and supply voltage. Standardized command inputs facilitate straightforward integration into plant programmable controllers.

Stackable sectional directional control assemblies HDF series architecture

HDF series sectional valves are designed for fluid power circuits in earthmoving equipment, agricultural machinery, drilling rigs, and lifting vehicles. The modular stackable build permits combining up to eight working sections with high-tensile tie-rods, establishing parallel or series flow paths.

Each working section can be equipped with manual levers, hydraulic pilot actuation, or electric solenoids. Built-in anti-cavitation and secondary pressure relief cartridges protect hydraulic motors from overload and pressure peaks during rapid deceleration, ensuring operational durability.

Explosion-proof fluid power engineering under ATEX regulatory standards

Operating hydraulic machinery in hazardous gaseous and dusty environments requires strict adherence to European directive ATEX 2014/34/EU. Aidro explosion-proof valves incorporate flameproof solenoid coil enclosures rated for thermal classes T5 and T6, preventing ignition of surrounding atmospheres.

The lineup includes spool directional valves, zero-leak poppet valves, and proportional units for chemical plants, fuel terminals, and offshore marine rigs. Exterior fasteners are fabricated from stainless steel, while the body features protective chemical plating against marine salt spray.

Additive manufacturing innovations in fluid power component production

Pioneering metal additive manufacturing allowed Aidro to achieve a technological leap in hydraulic component engineering. Fabricating HD2-AMES and HD3-AMES valve bodies via laser powder bed fusion and binder jetting bypasses traditional machining boundaries.

Internal curved galleries are formed with smooth sweeping radii without sharp ninety-degree angles, substantially decreasing fluid drag and heat generation.

Eliminating auxiliary cross-drillings and threaded plugs removes external leak risks, decreasing manifold weight by fifty percent with proof pressure resistance up to 700 bar.
