Product Overview
The Rexroth 4WRAP 6 W7-07-30-G24K4/M-00 (Material Number R900972658) is a high-performance proportional directional valve from the WRAP series, engineered for precise, continuous control of flow direction and magnitude in industrial hydraulic systems. This pilot-operated, two-stage valve utilizes a proportional solenoid to infinitely vary the spool position, enabling smooth, stepless regulation of actuator speed and direction. The 4WRAP design incorporates a position feedback loop for exceptional repeatability and dynamic response, making it ideal for demanding closed-loop applications where accurate velocity and force control are critical. As a direct OEM replacement, it ensures seamless integration into existing Rexroth-controlled machinery.

Engineering Features & Advantages
- Precision Proportional Control: The valve’s spool position is directly proportional to the electrical input signal, allowing infinite adjustment of flow rate and direction for accurate velocity profiling and smooth acceleration/deceleration.
- Integrated Position Feedback: A built-in inductive position transducer ensures high repeatability and minimal hysteresis, enabling stable closed-loop control of position, velocity, or force in servo-proportional systems.
- Robust Pilot-Operated Design: The two-stage configuration provides high flow capacity with low pilot pressure requirements, ensuring reliable operation even under varying load conditions.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM specifications, including mounting pattern, port connections, and electrical interface, minimizing downtime.
- Industrial Reliability: Constructed with hardened, precision-ground spools and sleeves for long service life and resistance to contamination, suitable for continuous operation in severe industrial environments.
Typical Industrial Applications
This proportional directional valve is widely used in heavy industrial scenarios requiring precise motion control, including: plastic injection molding machines (for injection
