Rexroth 4WE Series Solenoid Valve | 4WE6 & 4WE10 Directional Control Valve | 4WE10H 4WE6Y | High Pressure 350 Bar

Chengyuan Hydraulic offers high-performance 4WE series solenoid directional valves (available in Size 6 and Size 10), meticulously engineered to meet Rexroth industrial standards. This range includes flagship models such as 4WE6Y6X, 4WE6H6X, 4WE10J3X, and 4WE10H5X. As a slide-valve type control component, the 4WE series features wet-pin solenoids for high response and low-shock switching. Chengyuan guarantees 100% Drop-in Interchangeability in terms of ISO 4401 mounting interfaces, physical dimensions, and electrical logic (EG24 DC / EW230 AC). Backed by our rigorous 100% Simulation Load Testing, each valve is validated at 350 bar for sealing integrity and dynamic switching, providing a premium, cost-effective alternative to original Rexroth components.

Key Technical Advantages:

• Wet-Pin Solenoid Design: The armature moves within the system fluid, eliminating friction from dynamic seals. This ensures superior cooling and a service life exceeding 10 million cycles under high-frequency industrial conditions.

• High-Strength Cast Body: The valve housing is cast from high-grade ductile iron with CFD-optimized internal passages. This construction offers superior resistance to structural deformation under high pressure, effectively minimizing internal leakage.

• Precision-Ground Spools: Spools are crafted from heat-treated alloy steel and precision-ground to achieve micron-level fit. This ensures rapid switching while maintaining high pressure-holding accuracy in neutral positions.

• Optimized Shock Damping: The 4WE series is engineered for fluid power balance, significantly dampening hydraulic shocks during transition, which reduces system vibration and protects downstream components.

Application Areas:

• Machine Tool Industry: Directional control for CNC lathes, grinders, and automated machining lines.

• Plastic Machinery: Control for auxiliary circuits in injection molding machines and presses.

• Metallurgy Equipment: Rolling mill control systems and automated auxiliary hydraulic stations in steel plants.

• Mobile Machinery: Directional control logic for heavy-duty construction equipment.

Expert Maintenance Tips:

• Installation Orientation: Horizontal mounting is recommended. Vertical installation may affect response time or cause improper spool resetting due to armature weight.

• Fluid Cleanliness: To prevent spool jamming, maintain oil cleanliness at ISO 4406 18/16/13 or better. Dedicated return filtration is highly recommended.

• Electrical Safety: Never energize a solenoid coil unless it is properly mounted on the valve body; doing so will lead to excessive current draw and permanent coil damage.
