Product Description
Rexroth Type 4WRPH & 4WRPEH Series High-Response Proportional Directional Valves
Product Overview: The 4WRPH and 4WRPEH Series are high-performance, direct-operated proportional directional valves specifically engineered for closed-loop hydraulic circuits requiring extreme dynamic response and high-precision regulation. Available in Size 6 (NG6) mounting interfaces, these valves are widely used in injection molding machines, test benches, and aerospace simulation equipment. Their core strength lies in their ultra-short response times and exceptional flow linearity, ensuring system stability during high-speed operations.
This selection highlights the premium model 4WRPH6C3B12L-20 (0811404036), featuring integrated feedback to compensate for system variances in real-time.
Key Technical Advantages:
High Dynamic Frequency Response: Optimized solenoid drives provide servo-level switching frequencies, capable of accurately tracking high-frequency alternating command signals.
Integrated OBE (On-Board Electronics): Available with integrated amplifiers that are factory-calibrated, significantly enhancing signal integrity and simplifying system integration.
Servo-Quality Precision Spools: Spools and sleeves are precision-ground with zero or minimal overlap, ensuring a smooth transition during directional switching without dead-band effects.
Closed-Loop Feedback Reliability: An internal inductive transducer monitors spool position in real-time, maintaining superior repeatability even under continuous 315 Bar high-pressure conditions.
