Rexroth 4WE 4WREE Series Solenoid Valve | 4WE6 4WE10 4WREE10 | Directional Control Valve

The 4WE and 4WREE Series directional control valves from Chengyuan Hydraulic are high-performance components fully compatible with Rexroth industrial standards. The 4WE series utilizes wet-pin AC or DC solenoids for smooth switching without oil leakage risks, while the 4WREE series operates as a proportional directional valve with integrated LVDT position feedback for high-precision flow control. For core models such as 4WE10H, 4WE6D, and 4WREE10E, we utilize high-pressure resistant cast bodies. Every valve undergoes 100% simulated full-pressure switching tests before shipment to ensure no spool jamming or overheating under high-frequency operation, guaranteeing 100% original-place interchangeability.

Key Technical Advantages:

• Wet-Pin Solenoid Technology: The armature is completely immersed in oil, eliminating dynamic seals at the pushrod. This solves leakage issues and utilizes oil damping to reduce switching shock and noise.

• Optimized Flow Gallery Design: Through precision casting and polishing of internal channels, pressure drop (Δp) is minimized. Compared to standard replacements, our valves offer higher flow capacity and lower system temperature rise.

• High-Force Solenoid Coils: Utilizing high-purity copper windings and premium magnetic steel, the solenoids provide strong switching force, ensuring accurate spool reset even under low-temperature high-viscosity oil conditions.

• Proportional Control & Feedback (4WREE Features): The built-in LVDT position sensor monitors spool stroke in real-time. Paired with integrated electronics, it provides excellent linearity and minimal hysteresis, ideal for precision control loops.

Application Areas:

• Injection Molding: Precise switching for clamping and ejection sequences.

• Machine Tools: Hydraulic clamping and auxiliary control for CNC equipment.

• Metallurgical Equipment: High-frequency directional adjustment in steel mill automation.

• Presses & Brick Machines: Managing main circuit switching and proportional throttling.

Expert Maintenance Tips:

• Electrical Compatibility: Always verify the solenoid voltage (e.g., EG24 for DC 24V) before installation. Incorrect voltage will burn out the coil or result in failed switching.

• Fluid Filtration: Proportional valves (4WREE) require high oil cleanliness. We recommend systems be equipped with precision filters of NAS 7 (ISO 16/13) or better.

• Manual Override: The manual override buttons at the ends are for commissioning or emergency use only. Never lock them in place during normal production, as this may damage the internal return springs.
