Yuken DSG-02 Solenoid Valve | DSG-02-2B2-DL-D24 | Directional Control Valve

The DSG-02 Series solenoid directional valves from Chengyuan Hydraulic are versatile control components fully compatible with Yuken industry standards. Featuring a nominal size of 6 (NG6), these valves are renowned for their superior operational reliability powered by strong wet-pin solenoids. For core models like DSG-02-2B2-DL-D24 (2-position, spring offset, with D24 DC coil and indicator light), we have optimized internal casting galleries to significantly reduce pressure drops. Every valve undergoes 100% simulated high-frequency switching and internal leakage testing to ensure smooth shifting at 31.5 MPa, guaranteeing 100% original-place interchangeability.

Technical Specifications :

• Spool Functions: 2B2 (Spring offset, P blocked) / 3C2 (Spring centered, All blocked)

Key Technical Advantages:

• Powerful Wet-Pin Solenoid Technology: The armature is fully immersed in system oil, providing excellent lubrication and cooling while eliminating dynamic seal friction. This allows the DSG-02 to handle contaminants better and offers an exceptionally long electrical service life.

• High-Pressure, High-Flow Gallery: Optimized via CFD simulation, the internal structure minimizes pressure losses even at flow rates approaching 100 L/min. This improves overall hydraulic system efficiency and reduces heat generation.

• Leak-Proof Pole Tube Construction: A specialized sealing design for the pole tube ensures zero external leakage, even under high-frequency pressure spikes. The DL-type indicator light allows for rapid on-site troubleshooting of electrical signals.

• 100% Dynamic Shifting Validation: Chengyuan performs step-response timing tests on every batch. We ensure that DC24V coils provide reliable shifting even under 15% undervoltage conditions, maintaining consistency in mechanical operations.

Application Areas:

• Light Industrial Machinery: Automated packaging lines, textile machines, and injection molding auxiliary actions.

• Machine Tools: Clamping and tool-changing systems for grinders, modular machines, and CNC lathes.

• HPU Integration: Integrated valve blocks for various small-to-medium hydraulic power units.

Expert Maintenance Tips:

• Coil Specification Match: Always verify voltage ratings (D24 vs. A240) before replacement. Never energize an AC coil without the armature properly installed in the pole tube; doing so will cause excessive current and burn out the coil.

• Oil Viscosity Management: The DSG-02 operates best with oil temperatures between 15-70°C. For cold starts in winter, a pre-heating cycle is recommended to prevent sluggish shifting due to high viscosity.

• Mounting Bolt Torque: Use Grade 12.9 high-strength bolts and tighten to a torque of 5-7 N·m. Uneven or excessive tightening can warp the valve body, leading to spool binding.
