Product Overview
▔▔The Atos DKE series consists of heavy-duty, high-performance solenoid-operated directional control valves designed for subplate mounting (ISO 4401 size 10 / CETOP 05). Engineered for high-flow and high-pressure hydraulic systems, the DKE series delivers reliable directional control (on/off or fast-switching) of hydraulic fluid in demanding industrial applications. Available in both AC and DC solenoid configurations with optional wet-pin spool designs, the DKE series provides exceptionally low pressure drops, high functional limits, and superior switching dynamics.

- DC Supply: 12V DC, 24V DC, 110V DC, 220V DC
- AC Supply: 110V/50Hz, 120V/60Hz, 230V/50Hz, 240V/60Hz
Electrical Connection: Standard DIN 43650 / ISO 4400 connectors, optional AMP Junior-Timer, Deutsch, or lead wires.
Options & Accessories:
- Manual override buttons or hand levers for emergency actuation.
- Internal stroke limiters or switching time adjustments (damping orifice options).
- Built-in inductive proximity switches or position sensors for spool status monitoring (DKE-FI / DKE-IK models).
Key Materials and Components
▔▔
- Valve Body: High-grade shell-molded cast iron coated with anti-corrosion black conversion paint, providing reduced internal fluid turbulence and high fatigue resistance.
- Spool: Hardened and ground alloy steel precision machined to micro-inch tolerances to minimize internal leakage and prevent thermal binding.
- Solenoid Tubes: High-tensile stainless steel wet-armature pressure tubes designed to withstand continuous internal pressures without leakage.
- Seals: Standard NBR (Nitrile) for mineral oils; optional FPM (Viton/Fluoroelastomer) for synthetic fluids, phosphate esters, or elevated temperature conditions.
Packaging and Transport Protection
▔▔
- Individual Protection: Each valve is thoroughly tested, drained, treated with rust-inhibiting fluid, sealed in a heavy-duty moisture-proof anti-static vacuum bag, and protected with plastic port covers.
- Cushioning & Fixed Placement: Packed inside custom-molded shock-absorbing foam inserts or high-density honeycomb cardboard to prevent pin, connector, or spool damage during handling.
- Bulk Packaging: Multiple individual boxes are consolidated into ISPM-15 compliant export-grade wooden cases or reinforced corrugated master cartons, secured with heavy-duty polyester strapping and corner protectors for sea, air, or express freight.
Applications
▔▔- Plastic Injection Molding Machines: Controls clamping cylinder actuation and ejector movement, providing fast switching response and high cycle longevity.
- Metal Stamping and Hydraulic Presses: Manages main cylinder directional control, safety holding circuits, and pre-fill valve piloting under continuous high-pressure conditions.
- Steel Mill Machinery and Metallurgy Equipment: Executes heavy ladle tilting, roller table positioning, and continuous caster hydraulics, resisting harsh thermal environments and high duty cycles.
- Marine and Offshore Winches: Controls hydraulic motor rotation direction and braking systems, benefiting from robust corrosion resistance and high operating reliability.

FAQ
▔▔Q1: How do I correctly decode the complete model code for an Atos DKE valve?
A: The model code specifies the valve series (DKE), spool type (e.g., 1711, 1631), solenoid supply type and voltage (e.g., 24DC, 230AC), seal option (/V for Viton), and special options (e.g., manual override or stroke control). Please send us your complete code or nameplate photo for exact verification.
Q2: What cleanliness level is required for hydraulic oil used with DKE valves?
A: Fluid cleanliness should meet ISO 4401 class 18/16/13 or better. We recommend installing an online filter with a filtration accuracy of 10 to 25 microns to prevent spool clogging and ensure maximum service life.
Q3: Can standard NBR seals be used with phosphate ester or synthetic fire-resistant fluids?
A: No. Standard NBR seals are only suitable for mineral base oils and water-glycol mixtures. For synthetic fluids or phosphate esters, you must specify FPM / Viton seals (option /V).
