Rexroth 4WE10 Series Solenoid Valve | 4WE10C 4WE10J 4WE10D | CETOP 05 Directional Valve

The 4WE10 Series solenoid-operated directional spool valves by Chengyuan Hydraulic are high-performance control components fully compatible with Rexroth industrial standards. Featuring the Size 10 (CETOP 05) mounting interface, this series includes core models such as 4WE10C5X/EG24N9K4/M and 4WE10J33/CG24N9K4. These valves utilize high-power wet-pin solenoids for smooth switching and high flow capacity with minimal pressure drop. As a premium interchangeable solution, every 4WE10 valve offers 100% original-place interchangeability and undergoes 100% simulated condition testing—including switching frequency, leakage, and pressure drop tests—to ensure it meets the rigorous demands of industrial automation.

Technical Specifications:

• Core Models: 4WE10C, 4WE10J, 4WE10D, 4WE10E, 4WE10G

• Mounting Interface: CETOP 05 / ISO 4401-05 / DIN 24340

• Max Operating Pressure (Ports A/B/P): $31.5\text{ MPa (315 bar / 4570 psi)}$

• Max Operating Pressure (Port T): $21\text{ MPa (210 bar / 3050 psi)}$

• Max Flow Rate: $120\text{ to } 160\text{ L/min}$ (Depending on spool function)

• Solenoid Type: Wet-pin DC or AC solenoids (e.g., G24, W230)

• Electrical Connection: Individual plug-in connector (N9) or central connection

• Manual Override: Integrated push-button type (M)

Key Technical Advantages:

• Cast-Flow Optimization: The internal body galleries are designed with large cross-sections to reduce turbulence during high-speed flow. Compared to standard valves, the pressure drop is reduced by approximately $12\%$ at a flow of $120\text{ L/min}$, improving energy efficiency and lowering oil temperature.

• Heavy-Duty Wet-Pin Solenoids: The armature operates immersed in oil, providing superior damping and cooling. This reduces mechanical impact noise and significantly extends the life of the solenoid under $100\%$ duty cycle, supporting switching frequencies up to $15,000$ cycles/hour.

• Precision-Ground Spools: Spools undergo multi-stage precision grinding to micron-level tolerances. Combined with high-quality return springs, this ensures rapid and accurate centering upon de-energization, with internal leakage rates well below industry standards.

• Vibration-Resistant 5X Design: The 5X series features reinforced spool guidance and spring structures, maintaining stable switching response in high-vibration environments such as injection molding machines and heavy presses.

Application Areas:

• Metalworking: Logic control circuits for hydraulic presses, shearing machines, and CNC press brakes.

• Plastic Machinery: Control for core pulling, carriage movement, and mold locking.

• Hydraulic Power Units: Used as the central direction control unit in integrated manifold blocks.

Expert Maintenance Tips:

• Mounting Surface Accuracy: Ensure the manifold mounting surface flatness is better than $0.01/100\text{ mm}$. An uneven surface can distort the valve body when bolts are tightened, causing the spool to jam.

• Electrical Safety: For G24N9 (24V DC) models, verify that the plug-in connector gaskets are properly seated to maintain an IP65 rating and prevent short circuits from moisture or coolant.

• Switching Shock: In high-pressure/high-flow systems, if excessive switching shock occurs, consider adding orifices in the P-port or A/B-ports to smooth the transition.
