Atos DHI 0713 23

Product Overview

The Atos DHI-0713 23 is a high-performance, spool-type, direct-operated 4/3-way solenoid directional control valve belonging to the renowned Atos DHI series. Designed for subplate mounting on ISO 4401 size 06 (CETOP 3) interfaces, this valve regulates fluid flow direction in high-precision hydraulic circuits. Operating via high-efficiency wet-pin AC or DC solenoids, the DHI-0713 23 ensures rapid, repeatable spool switching and precise directional management in demanding industrial automation and hydraulic equipment.

Key Advantages

• High-Flow & Pressure Capability: Engineered for system working pressures up to 350 bar and nominal flow rates up to 60 L/min.
• AC/DC High-Performance Solenoids: Features threaded wet-pin solenoids with easy coil replacement without oil loss or system depressurization.
• Compact ISO Standard Interface: Fully compliant with ISO 4401-03-02-0-05 and CETOP 3 standards for simple integration and cross-brand interchangeability.
• Reliable Switching Dynamics: Optimally machined spool lands deliver precise flow control, reduced hysteresis, and long functional operational life under heavy-duty cycles.

• Feedback Mechanism: Standard version operates open-loop; optional inductive position switches or electronic monitor switches are available for safety-critical applications.
• Nominal Flow Rating: Configured for maximum flows up to 60 L/min, optimized with low Δp flow paths.
• Mounting Pattern: ISO 4401-03 subplate interface utilizing standard M5 metric mounting screws.
• Electrical Connection: Standard 3-pin DIN 43650 (ISO 4400) plug connectors with IP65 ingress protection when properly installed. Optional LED illuminated plugs and surge suppressors available.

Key Materials and Components

▔▔

• Valve Body: High-grade cast iron body with shell-molded internal fluid passages designed for minimal pressure drop and maximum volumetric efficiency.
• Control Spool: Hardened steel spool precision-ground to micrometer tolerances to minimize internal fluid leakage and prevent dynamic binding under thermal stress.
• Solenoid Tubes & Armor: Heavy-duty carbon steel and stainless steel pressure-tight armatures designed for dynamic hydraulic forces and frequent impulse cycling.
• Seals: Standard NBR (Nitrile) static and dynamic seals compatible with mineral oils, water-glycol fluids, and synthetic hydraulic fluids. Optional FKM (Viton) seals available for high-temperature or phosphate ester fluid applications.

Packaging and Transport Protection

▔▔

• Industrial Protection: Each valve is thoroughly tested, dried, treated with anti-rust oil, and hermetically sealed in dust-proof plastic packaging.
• Moisture & Shock Resistance: Vacuum-sealed with silica gel desiccant packs inside impact-resistant individual cardboard cartons with molded foam liners.
• Secured Transport: Valves are reinforced with internal cardboard stabilizers to protect solenoid pins and electrical contacts from vibration during air or sea transport.
• Bulk Packaging: Multi-unit orders are stacked on standardized, heat-treated wooden or plastic pallets, reinforced with edge guards, and fully wrapped in industrial stretch film with heavy-duty strapping.

Applications

• Plastic Injection Molding Machinery: Controls core pullers, ejector pins, and auxiliary hydraulic cylinder directional strokes where precise timing and cycle repeatability are critical.
• Metal Stamping & Hydraulic Presses: Regulates pre-fill pilot operations, clamp closing movements, and hydraulic safety interlocks under continuous high-pressure conditions.
• CNC Machine Tools & Workholding: Manages hydraulic chuck clamping, tailstock movement, and pallet changer drive cylinders requiring leak-free lock-up and rapid response.
• Industrial Automation & Material Handling: Used in automated hydraulic lifters, transfer arms, and indexing tables requiring dynamic directional control.

FAQ

What types of hydraulic fluid are compatible with the DHI-0713 23?

The standard NBR seal version works with mineral-based hydraulic oils (HL, HLP) according to DIN 51524. For fire-resistant fluids (like phosphate esters), request the Viton (FKM) seal variant (suffix /PE).

Can I directly replace a DHI valve with a standard CETOP 3 valve from another brand?

Yes, the Atos DHI-0713 23 adheres strictly to the ISO 4401-03 / CETOP 3 mounting pattern. However, ensure that the spool functionality (713 type), coil operating voltage, and electrical connector type match your control circuit scheme.
