DKE-1631/2 Atos Solenoid Valve 315bar

Model Number	DKE-1631/2/A-X 230RC, DKE-1631/2 DC 20/PE /DC10 24VDC, DKE-1631/2/A

Product Description

Product Overview

The DKE-1631/2 is a premium-grade, direct-acting, spool-type directional solenoid valve built strictly to the ISO 4401 standard (NG10 / CETOP 05 size). Engineered for highly demanding high-pressure and high-flow hydraulic systems, this valve offers 100% precise interchangeability with the original Atos DKE/DKER series. Available in both 24VDC and 230RC (rectified AC) coil variants, every single valve undergoes 100% simulated operational condition testing before dispatch. We guarantee factory-level switching accuracy, virtually zero internal leakage, and uncompromising durability under extreme load environments, making it the ultimate aftermarket upgrade for your industrial machinery.

Key Technical Advantages

Flawless Interchangeability: Manufactured with exacting tolerances to match ISO/CETOP standards perfectly. This allows for a 100% drop-in replacement for any existing Atos DKE-1631/2 valve without any need to modify hydraulic lines or subplates, drastically reducing system downtime.
Micron-Level Precision Machining: The valve spool and cast housing bore undergo advanced compound honing processes. This ultra-tight clearance dramatically minimizes internal fluid leakage at high pressures, elevating volumetric efficiency and ensuring rapid, crisp spool shifting.
Durable Wet-Pin Solenoid Architecture: Equipped with fully enclosed wet-pin solenoids, the moving armature operates directly within the system’s hydraulic fluid. This design provides excellent coil cooling, cushions switching impacts for whisper-quiet operation, and significantly extends the service life of internal moving parts.
100% Simulated Condition Testing: We leave nothing to chance. Every unit is strictly tested on our simulation benches under peak 315 bar pressure, maximum flow rates, and high-frequency shifting scenarios to ensure zero defects and rock-solid reliability before it reaches your facility.

Application Areas

Plastic injection molding machinery (core injection/clamping circuits)
Heavy-duty metal stamping and forging presses
Construction equipment and mobile hydraulic lifting platforms
CNC machine tools and centralized Hydraulic Power Units (HPUs)

Expert Maintenance Tips

Subplate Preparation: Before installation, meticulously verify that the mounting subplate surface flatness is within 0.01/100 mm and the surface roughness does not exceed Ra 0.8. Poor surface finish is the leading cause of O-ring extrusion and external leakage under 315 bar operations.
Fluid Cleanliness: Maintain hydraulic fluid cleanliness to ISO 4406 class 20/18/15 or better. Solid contamination is the primary cause of spool binding. In solenoid valves, a jammed spool prevents full stroke, which causes the coil to draw excessive current and ultimately leads to premature coil burnout.
