DSG-01-3C2-D24 Yuken Solenoid Directional Valve 350bar

Product Overview

Models such as DSG-01-3C2-D24-50905, DSG-01-3C2-D24 and DSG-01-2B2 belong to the Yuken DSG-01 series of solenoid operated directional valves. Featuring wet-type solenoid actuation of a spool valve, they comply with ISO 4401-03 (NG6 / CETOP 3) mounting standards. Every unit undergoes rigorous 100% simulated operating-condition testing and offers excellent drop-in interchangeability with equivalent solenoid directional valves. High pressure, high flow and low pressure drop design make them ideal for directional control in modern industrial hydraulic systems.

Key Technical Advantages

1. High pressure and high flow design: Rated up to 35 MPa and 100 L/min to meet the demands of modern high-pressure hydraulic systems.
2. Low pressure drop: Optimized flow passages reduce pressure loss by approximately 10%, helping lower system energy consumption.
3. Excellent drop-in interchangeability: Strict compliance with ISO 4401 mounting face allows direct replacement of equivalent Yuken or other brand directional valves, minimizing modification costs and downtime.
4. Wet-type solenoid for long life: Coil immersed in oil provides excellent heat dissipation and low noise, suitable for continuous duty.
5. Optional shockless type: S-type versions offer soft shifting to reduce switching shock and noise.

Application Areas

Injection moulding machines, die-casting machines, metal-forming equipment, machine-tool hydraulics, packaging machinery, automated production lines, mobile equipment and other medium-to-high-pressure hydraulic circuits requiring reliable directional control.

Expert Maintenance Tips

1. Ensure mounting surfaces are clean and flat before installation; fit seals correctly and tighten specified bolts evenly to the recommended torque to prevent external leakage.
2. Maintain recommended fluid cleanliness; use hydraulic fluids compatible with the installed seal material.
3. Use shielded cables for electrical connections and ensure supply voltage is within the rated range; verify correct coil wiring before first start-up.
4. Periodically inspect the valve body and solenoids for overheating or leakage; clean and protect mounting surfaces during long-term storage.
5. Do not disassemble the spool or solenoid assemblies. Coil or seal replacement should be performed only by technicians experienced with Yuken products; always perform functional tests before returning the valve to service.
