4WRDE25/7/4WRLE16/4WRPEH10 REXROTH Hydraulic Valves Control Directional Proportional Valve Pilot Operated

This selection of REXROTH proportional directional valves represents high-precision electro-hydraulic control for demanding industrial and mobile applications. These pilot-operated, electrically controlled valves provide infinitely variable and precise control over the direction, volume, and pressure of hydraulic flow to actuators.

The 4WRDE and 4WRLE series are high-performance proportional valves known for their excellent dynamic response and accuracy. The 4WRPEH10 cartridge valve version offers a compact, manifold-mounted solution for space-constrained systems. All are designed for seamless integration with electronic control systems (e.g., PLCs) for automated, smart hydraulic functions.

Key Features & Benefits:

• Proportional Control: Delivers smooth, infinitely variable spool shifting for precise control of cylinder and motor speed and direction, eliminating shock and improving cycle times.

• Pilot-Operated Design: Uses a low-power solenoid to control a pilot stage, which then hydraulically shifts the main spool. This allows for efficient control of high flow rates with a compact electrical interface.

• High Performance & Accuracy: Excellent hysteresis and repetition accuracy ensure consistent, repeatable machine performance crucial for automation and process control.

• REXROTH Quality: Engineered and manufactured to the highest industry standards for reliability, durability, and long service life in harsh environments.

• Application Versatility: Ideal for use in machine tools, injection molding machines, press controls, test stands, and mobile equipment where precise motion control is critical.
