Product Overview
▔▔The Atos SDHE Series is a high-performance, spool-type solenoid directional control valve designed for precise fluid direction management in medium-to-high pressure industrial hydraulic systems. Positioned as a premier CETOP 03 (NG6) direct-operated valve series within the Atos hydraulic component line, the SDHE series offers fast response, minimal internal leakage, and robust reliability under continuous dynamic loads.
Key Advantages
▔▔- High Flow Capacity: Optimized internal flow passages minimize pressure drops while supporting high system throughput.
- Wet-Pin Solenoids: Threaded, high-efficiency wet-pin AC/DC solenoids provide smooth operation, low operating noise, and easy coil replacement without opening the hydraulic circuit.
- Versatile Spool Configurations: Available with a wide range of standard and custom spools (3-position, 2-position) for flexible circuit design.
- Extreme Durability: Precision-ground spools and hardened valve bodies ensure extended service life and consistent hysteresis performance.

Applications
▔▔- Individual Protection: Every valve is treated with anti-rust oil, sealed inside an anti-static vapor corrosion inhibitor (VCI) polybag, and wrapped in protective foam.
- Moisture & Contamination Control: Ports are fitted with custom plastic dust caps to preserve clean internal surfaces until installation. Moisture-absorbing desiccant packs are enclosed in every primary package.
- Shock & Vibration Prevention: Valves are packed in individual reinforced corrugated cardboard boxes with contoured shock-absorption inserts to prevent mechanical damage during transit.
- Bulk & Export Shipping: Individual boxes are packed into heavy-duty master cartons and strapped onto fumigated wooden or plastic pallets. Master pallets are fully stretch-wrapped and corner-protected for long-distance sea or air freight.

FAQ
▔▔Q1: What is the primary difference between Atos SDHE and DHI/DHE series directional valves?
Answer: The SDHE series is a high-performance series designed for working pressures up to 350 bar and flow rates up to 80 L/min, featuring optimized internal body casting and heavy-duty solenoids. Standard DHI/DHE valves are designed for lower flow or general-duty applications (typically lower pressure limits or smaller flow margins). SDHE offers higher operational margins and faster response times in severe duty cycles.
Q2: Can the solenoid coil on the Atos SDHE-0713 be replaced without shutting down the hydraulic system?
Answer: Yes. The SDHE series utilizes wet-armature solenoids with sealed retaining tubes. You can unscrew the coil retaining nut, remove the electrical coil, and install a replacement coil without opening the hydraulic fluid chamber or relieving circuit pressure.
