Duplomatic DSE3 Proportional Directional Valve | DSE3-C16SA/11N-D24K1 | NG6 CETOP 3

LIC Hydraulic’s Duplomatic DSE3 Series proportional directional valves are premium components designed for precise control of fluid flow and direction. The specific model DSE3-C16SA/11N-D24K1 is a direct-operated valve with a CETOP 03 (NG6) interface. It translates electrical proportional signals into exact mechanical spool displacement, allowing for stepless speed and position control of hydraulic actuators. We guarantee 100% Drop-in Interchangeability with OEM specifications. Every unit undergoes rigorous 100% dynamic load and linearity testing to ensure laboratory-grade precision in demanding industrial automation environments.

Key Technical Advantages

• Linear Proportional Solenoids: Equipped with high-performance wet-type proportional solenoids that deliver a superior current-to-force ratio, ensuring smooth flow modulation and minimized hysteresis for precise automation.

• Precision-Ground Spool: The spool is crafted from hardened alloy steel and ground to micron-level tolerances. This ensures exceptional center-position accuracy and high resistance to wear and fluid contaminants.

• CFD-Optimized Geometry: The “C” type spool profile is optimized for stable flow characteristics across the entire stroke, reducing turbulence and hydraulic shock during direction reversals.

• High Pressure Density: With a 350-bar rating on pressure ports, the DSE3 delivers high power density in a compact NG6 footprint, ideal for space-constrained manifold assemblies.

Application Areas

• Machine Tools: Stepless feed speed regulation and precise tool movement control.

• Plastic Machinery: Pressure compensation in injection molding and synchronized motion in blow molding.

• Steel Industry: Tension control systems and oscillation table drives in continuous casting.

• Simulation Rigs: Dynamic load simulation and high-frequency hydraulic actuator testing.

Expert Maintenance Tips

• Electronic Control: Always use a PWM-enabled proportional amplifier. Proper Dither frequency adjustment is critical to overcoming mechanical stiction and ensuring the highest responsiveness of the spool.

• Fluid Cleanliness: To prevent spool jamming or premature wear, maintain system oil cleanliness at ISO 4406 18/16/13 or better. High-performance filtration is non-negotiable for proportional systems.

• Air Bleeding: Ensure all air is bled from the hydraulic circuit and the solenoid tubes (via the vent screw if applicable) during initial commissioning to prevent erratic “spongy” control.
