Rexroth 4WE6 Hydraulic Directional Control Valve - 6mm Size, 315 Bar Pressure, 40 L/min Flow for Industrial Machinery
The 4WE6 Electromagnetic Directional Valve is a compact sliding valve directional control valve controlled by wet electromagnet, designed for industrial hydraulic systems.
Utilizes electromagnetic force to drive the valve core movement, changing hydraulic oil circuit direction to control hydraulic actuator components including cylinder extension/retraction and motor start/stop/forward/reverse rotation.
- Compact structure with small size and high power density
- Wet electromagnetic coil for long service life and stable operation
- ISO 4401 standard compliance with uniform installation dimensions
- Excellent interchangeability across hydraulic systems
- Multiple voltage, slide valve function, and operation mode options

The valve operates through electromagnetic actuation and spring return mechanism:
- Initial State: Valve core remains in neutral position via reset spring
- Activation: Electromagnet energizes, generating force to move valve core
- Oil Circuit Switching: Core movement changes port connections (e.g., P→A, B→T for cylinder extension)
- Reset: Spring force returns valve core to neutral when power is cut
- Emergency Operation: Manual push rod allows direction changes during power failure for system debugging
Ideal for small to medium power industrial hydraulic equipment across multiple sectors:
- Machine tools: Tool holders, workpiece clamping for machining centers, grinders, stamping machines
- Plastic machinery: Injection molding machine stage movement, mold closing control
- Construction equipment: Small excavators, forklifts, lifting platforms
- Metallurgical equipment: Steel rolling auxiliary systems, strapping machines
- Agricultural machinery: Tractors, harvesters hydraulic systems
- Automation equipment: Fixtures, handling robots, industrial automation
