Key Technical Advantages:

• Geometric Flow Path Optimization: The valve body features high-precision internal casting. Optimized flow channels significantly reduce pressure drop (Δp), enhancing system energy efficiency and minimizing oil temperature rise.

• High-Hardness Wear-Resistant Spool: Spools are crafted from high-alloy steel with multi-stage heat treatment (HRC 60+). Precision grinding ensures micron-level clearances between the spool and housing, drastically reducing internal leakage.

• Wet-Pin Solenoid Design: The armature moves in oil, eliminating dynamic seal friction. This provides superior heat dissipation and dampens shifting impact, greatly extending the service life and allowable switching frequency (up to 15,000 cycles/h).

• Voltage Fluctuation Tolerance: Specifically designed for industrial grid variability, Chengyuan’s optimized coils allow stable operation within a ±10% voltage range, ensuring precise actuation in harsh or unstable electrical environments.

Application Areas:

• Injection Molding Machinery: Precise direction control for injection and mold clamping.

• Metallurgical Equipment: Pressure distribution and motion control in rolling mill auxiliary systems.

• Hydraulic Presses: Main switching circuits for four-column presses, balers, and shearing machines.

• Mobile Machinery: Hydraulic power unit control for drilling rigs, pump trucks, and sanitation equipment.

Expert Maintenance Tips:

• Filtration Requirements: The 4WE10 is a precision valve. Maintain system oil cleanliness at ISO 4406 20/18/15 or better to prevent spool sticking or premature wear.

• T-Port Pressure Limitation: Ensure the backpressure at Port T does not exceed 16MPa. Excessive backpressure can lead to sluggish solenoid response or failure of the manual override.

• Coil Safety: Never energize the solenoid coil when it is removed from the valve body. This will lead to instantaneous overheating and permanent coil failure.
