Atos Solenoid Valve | DHI-0711-24DC | DHE-0711/WP | DHI-0631 | DHI-0630 | NG6 Directional Valve

Atos DHI & DHE Series Direct-Acting Solenoid Directional Valves

Product Overview: The Atos DHI and DHE series are the industry standards for directional control in high-performance hydraulic systems. The DHI series serves as a versatile, cost-effective solenoid valve for a wide range of industrial applications, while the DHE series is the high-performance variant designed with superior electromagnetic force and higher switching limits. Engineered with wet-pin technology and rated for pressures up to 350 bar, these valves are the primary choice for 2026 automated machine tools, injection molding machinery, and industrial power units.

Featured models: DHI-0711-24DC, DHE-0711/WP, DHI-0631/2/A-23, and DHI-0630/2/A-23.

Key Technical Advantages:

• High-Performance Solenoid Drives: * DHI Series: Utilizes standard digital AC/DC solenoids with low power consumption and heat emission.

  • DHE Series: High-performance version with enhanced magnetic force to ensure reliable switching under high-pressure and high-flow conditions.

• WP Enhanced Protection (Waterproof): Models with the WP suffix feature advanced water and corrosion resistance, ideal for humid or harsh industrial environments.

• Versatile Spool Configurations: Available in 0711 (2-position), 0631/0630 (3-position), and other logic combinations to meet requirements from simple direction changes to complex load holding.

• Optimized 20/23 Design Sequences: Incorporating Atos’s latest 20 and 23 design sequences, the internal channels are CFD-optimized to minimize pressure drops and extend operational life.

• Wet-Pin Armature Construction: The armature operates within oil for excellent self-lubrication and damping, significantly reducing switching noise and mechanical wear.
