DSE5J-C80/10N-E0K11/C Duplomatic Proportional Directional Valve 320bar

Product Overview

The DSE5J-C80/10N-E0K11/C is a Duplomatic direct-operated proportional directional control valve featuring position feedback (LVDT) and on-board digital electronics (OBE). Designed to ISO 4401-05 (CETOP 05) mounting standards, it precisely modulates the direction and speed of hydraulic actuators. Every unit undergoes 100% simulated operating-condition testing and offers excellent drop-in interchangeability with equivalent CETOP 05 proportional valves. The closed-loop architecture delivers exceptionally low hysteresis and high repeatability, making it ideal for demanding industrial hydraulic systems that require consistent dynamic performance and positioning accuracy.

Key Technical Advantages

1. Closed-loop position feedback with digital OBE: Integrated LVDT and digital driver card enable precise closed-loop spool positioning, achieving hysteresis below 0.2% and repeatability better than ±0.1%—significantly superior to open-loop proportional valves.
2. High dynamic response and pressure gain: Excellent pressure gain at low command signals allows rapid compensation for external disturbances and short response times, ideal for fast directional changes and accurate speed control.
3. Precision machining and long service life: High-accuracy valve body and spool manufacturing combined with quality seals deliver high volumetric efficiency, low internal leakage, and reliable long-term operation with extended maintenance intervals.
4. True drop-in interchangeability and easy installation: Strict compliance with ISO 4401-05 mounting face and standardized electrical interface, plus simplified wiring via on-board electronics and software-adjustable parameters, enable direct replacement of equivalent valves and minimize system downtime.
5. Comprehensive diagnostics and protection: Built-in safeguards against overload, overheating, sensor failure, cable break, and supply voltage faults, together with real-time spool-position monitoring, enhance system reliability and serviceability.

Application Areas

Injection moulding machines, die-casting machines, metal-forming equipment, plastics machinery, machine-tool hydraulics, metallurgical equipment, mobile machinery actuator control, automated production lines requiring precise cylinder or motor direction/speed control, and other medium-to-high-pressure hydraulic systems demanding closed-loop proportional performance.

Expert Maintenance Tips

1. Verify mounting surface flatness and roughness before installation; tighten the four M6 bolts to the specified torque (approx. 8 Nm) and fit seals correctly to prevent external leakage.
2. Maintain fluid cleanliness to ISO 4406 18/16/13 or better; use HL/HM mineral oil with NBR seals. Thoroughly bleed the system before first start-up to avoid cavitation and noise.
3. Use shielded cables for electrical connections, separate signal and power lines, and ensure EMC compliance. After power-up, verify monitor signals; use the optional LINPC-USB kit for diagnostics and parameter adjustment when required.
4. Periodically inspect solenoid temperature and connector sealing integrity; never exceed recommended fluid temperature. Clean and protect the valve during long-term storage and perform functional/leak tests before recommissioning.
5. Do not disassemble the position transducer or electronics housing, as this will invalidate factory calibration. Spool or seal replacement should be performed only by technicians experienced with Duplomatic products.
