Atos DHI 0610 23

Product Overview

The Atos DHI 0610 23 is a high-performance, AC/DC solenoid-operated directional spool valve engineered for precise fluid direction control in industrial hydraulic systems. As part of the renowned Atos DHI series (CETOP 03 / ISO 4401 size 06), this direct-operated valve delivers reliable switching performance, low pressure drops, and exceptional system stability. It is specifically designed for high-frequency dynamic switching and precision pressure/flow directional management in demanding hydraulic circuits.

Key Advantages

• High Efficiency Solenoids: Features wet-pin AC or DC solenoids with threaded tubes for fast response times and smooth spool shifting.
• Compact Subplate Mounting: Adheres strictly to ISO 4401-03 standards, ensuring easy integration, compact footprint, and leak-free mounting.
• Low Pressure Drop: Optimized internal flow passages reduce energy loss and fluid heat generation.
• High Operational Reliability: Designed to perform consistently under elevated pressure levels and continuous duty cycles.

Key Materials and Components

▔▔

• Spool Material: Hardened and ground steel designed for minimal clearance wear, reduced fluid leakage, and resistance to cavitation erosion.
• Valve Body: High-tensile shell-moulded cast iron with precision-machined internal galleries to maximize flow capacity and minimize drop in hydraulic pressure.
• Seals: Standard NBR (Nitrile) seals suitable for mineral oils and synthetic fluids; optional FKM (Viton) seals for high-temperature operations or fire-resistant fluids.
• Solenoid Armature Tube: Threaded wet-pin steel tube designed for high burst pressure safety and rapid heat dissipation during continuous operation.

Packaging and Transport Protection

▔▔

• Primary Protection: Anti-corrosion oil application followed by vacuum-sealed moisture-proof plastic wrapping.
• Shock Absorption: Customized high-density EPE foam cradles within individual inner boxes to protect solenoids and mounting faces from vibration or impact.
• Bulk Packaging: Multi-unit orders are consolidated in reinforced corrugated cartons or wooden crates, strapped securely, and palletized with stretch wrap for safe fork-lift handling.

Applications

• Plastic Injection Molding Machines: Controls main clamping cylinder movement and core-puller directional sequences for precise mold locking.
• Metal Stamping Presses: Manages hydraulic press die actuation, holding routines, and emergency retract circuits.
• CNC Machine Tools: Executes quick hydraulic clamping, indexing table rotation directional control, and tool changer positioning.
• Metallurgical Equipment: Controls hydraulic side guides, tilt tables, and furnace door actuation in steel processing lines.

FAQ

Q1: How do I confirm the correct full model code before ordering?

A: Check the serial plate on your current valve or verify the spool type, voltage (e.g., 24VDC vs 220VAC), electrical connector type, and seal material required for your system.

Q2: What filtration level is recommended for optimal performance?

A: We recommend fluid cleanliness of ISO 4406 class 20/18/15 or better (using a filter rating of 25 microns or finer) to prevent spool sticking and valve orifice clogging.
