Yuken DSG-02 Series Solenoid Valve | DSG-02-3C2-D24-N1-50 | CETOP 03 Directional Valve

The DSG-02 Series solenoid-operated directional valves by Chengyuan Hydraulic are high-performance spool valves fully compatible with Yuken industrial standards. Featuring the standard Size 6 (CETOP 03) mounting interface, this series includes the core model DSG-02-3C2-D24-N1-50 (3-position, 4-way, closed-center function). Driven by optimized high-power wet-pin solenoids, these valves offer high switching reliability, low pressure drop, and superior water/dust protection (IP65). As a premier interchangeable solution from Chengyuan, all units provide 100% original-place interchangeability and undergo 100% simulated condition testing to ensure stable switching performance at pressures up to 31.5MPa.

Key Technical Advantages:

• High-Force Solenoid Technology: Features powerful wet-armature solenoids that guarantee reliable switching even in conditions with minor oil contamination or high fluid viscosity. The oil-immersed design eliminates impact noise and drastically improves coil heat dissipation.

• Low Pressure Drop Flow Paths: The valve body is precision-cast with hydrodynamically optimized internal galleries. This reduces internal pressure drop by approximately $10\%$ compared to standard alternatives, minimizing system heat generation and enhancing energy efficiency.

• Precision-Mated Spools: Spools are micro-ground and deburred to achieve extremely tight tolerances. This ensures minimal internal leakage and significantly reduces wear during long-term high-frequency operation, with a service life exceeding 10 million cycles.

• All-Weather Protective Structure: Robust end-covers and high-quality seals provide excellent moisture and dust resistance. The N1 terminal box features a transparent cover and LED indicators for easy status monitoring and rapid on-site troubleshooting.

Application Areas:

• Automated Production Lines: Directional control for conveyors and loading/unloading mechanisms.

• Industrial Presses: Core directional control for small hydraulic presses and brake machines.

• Material Handling: The primary distribution valve in lifting platforms and stacker hydraulic systems.

Expert Maintenance Tips:

• Voltage Regulation: Maintain input voltage within $\pm 10\%$ of the rated value. Persistent low voltage can lead to incomplete spool movement, while high voltage may shorten coil life.

• Mounting Torque: Ensure the mounting subplate is clean and flat. Tighten mounting bolts to a torque of $5\text{ to } 7\text{ Nm}$. Uneven tightening can lead to valve body distortion.

• Fluid Cleanliness: Although the DSG-02 is robust, we recommend regular oil changes and maintaining a $10\mu\text{m}$ filtration rating to prevent fine particles from damaging the precision control edges of the spool.
