The REXROTH 4WRZE16W6-100-74/6EG24N9ETK31/F1M is a heavy-duty industrial proportional directional valve engineered for precise, continuous control of flow direction and magnitude in high-pressure hydraulic systems. As part of the Rexroth 4WRZE series, it utilizes a pilot-operated, two-stage design with integrated position feedback to deliver accurate spool positioning proportional to the electrical input signal.

Key Engineering Features
- Two-stage pilot-operated design with main spool position feedback for high accuracy and repeatability.
- Integrated on-board electronics (OBE) with factory-calibrated current controller for simplified commissioning.
- W6 spool profile provides progressive flow gain, ideal for smooth acceleration and deceleration control.
- Rugged cast iron housing and hardened spool for long service life in demanding industrial environments.
- Fail-safe spring return to center position on power loss or signal interruption.
- Compatible with Rexroth proportional amplifier modules and standard PLC analog outputs.
Industrial Applications
- Injection molding machines – clamp, injection, and ejector axis control.
- Hydraulic presses – force and position regulation.
- Steel and metal forming – roll gap and tension control.
- Marine and offshore – winch and crane drive systems.
- Test rigs and simulators – dynamic load and motion control.
- General industrial automation – high-cycle proportional actuation.
