Key Technical Advantages:

• High-Pressure Architecture: Constructed from high-strength cast iron with precision-polished internal fluid paths. This design minimizes flow resistance at high volumes and ensures smooth, accurate switching even at rated pressures of 31.5 MPa.

• High-Reliability Solenoids: Solenoid assemblies feature vacuum-impregnated insulation for superior moisture and dust protection. Optimized push-pin geometry reduces energy loss, significantly extending continuous-duty cycles without coil degradation.

• Precision Tolerances: Spool-to-bore clearances are held to micron-level tolerances. This superior fit ensures excellent internal sealing under high-pressure loads, effectively eliminating actuator pressure drops and switching delays.

• Modular Compatibility: Designed for global standard mounting dimensions. Whether retrofitting legacy machinery or integrating into new systems, these valves offer “plug-and-play” convenience, requiring no modification to existing subplates.

Application Areas:

• Automated Manufacturing: Hydraulic control for CNC machinery and automated assembly lines.

• Construction Machinery: Power control for crushing equipment and hydraulic outrigger systems.

• Injection Molding: Pilot control loops and auxiliary fluid routing.

• Industrial Presses: Precision action execution for punch presses and metal-forming machinery.

Expert Maintenance Tips:

• Fluid Cleanliness Management: With minimal spool clearance, 3WE valves are highly sensitive to contaminants. Maintain fluid cleanliness at ISO 4406 18/16/13. We strongly recommend a 10μm pressure-line filter.

• Voltage Verification: Always confirm exact voltage specifications (e.g., AG24 or CG24) before wiring. Over-voltage causes coil overheating, while under-voltage results in insufficient magnetic force to actuate the spool.

• Mounting Integrity: Ensure the subplate is clean and free of burrs. Always install with new, correct-spec O-rings and tighten mounting bolts in a cross-pattern to ensure uniform pressure, preventing valve body deformation and spool binding.
