DSE3-A26/10N-D24K1 Proportional Directional Valve

Product Overview

The DSE3-A26/10N-D24K1, DSE3-A04/11N-D24K1, DS3, DS5, DS, DSE, DSE3 and DSE5 belong to the proportional solenoid directional control valve series (exemplified by Duplomatic DSE3). These direct-operated proportional directional valves feature ISO 4401-03 (CETOP 03) subplate mounting and regulate spool opening and flow in proportion to the input current for precise direction and speed control of hydraulic actuators. Fully interchangeable with original units, every valve undergoes 100% simulated operating-condition testing for accurate proportional control in hydraulic systems.

Key Technical Advantages

1. Precise proportional control: Spool opening and flow are proportional to input current, enabling stepless direction and speed regulation.
2. Low hysteresis and high repeatability: Hysteresis < 6% and repeatability ±1.5% ensure stable and reliable control.
3. High interchangeability: Identical interfaces and performance to original DSE3 series enable direct drop-in replacement.
4. 100% functional verification under simulated conditions: Every unit is fully tested across current-flow characteristics before shipment, ensuring consistency.

Application Areas

• Proportional control on injection molding and die-casting machines
• Machine tool feed and positioning systems
• Actuator speed control on construction machinery
• Precise direction and flow regulation in industrial hydraulic power units
• Open- or closed-loop systems requiring electro-proportional control

Expert Maintenance Tips

Ensure the mounting surface is clean and flat; tighten to the specified torque. Maintain fluid cleanliness at ISO 4406 18/16/13. Match solenoid voltage and PWM signal correctly. Periodically check null and proportional characteristics. If hysteresis increases or flow becomes unstable, first inspect fluid contamination and filters. For long-term storage keep the valve filled with oil. Always use original-specification seals when servicing.
