The Bosch Rexroth 4WRLD27W600LJ-4X/MXY/24WD6T-151 (R901437973) is a state-of-the-art digital directional control valve with an integrated axis controller, designed to deliver precise control and high responsiveness in a variety of applications. This valve offers multifunctional capabilities including position control, pressure-force control, closed-loop speed control, and substitutional closed-loop control for position-pressure and flow-pressure. The 4WRLD27W600LJ-4X/MXY/24WD6T-151 is capable of operating in several modes such as valve direct control and drive-controlled positioning, with command values preset via Ethernet or analog-digital interfaces. The unit comprises a pilot control valve and a main stage with centering springs and position feedback, ensuring high-quality servo performance. It features multiple Ethernet interfaces (XE1, XE2), analog sensor inputs (XM1, XM2), a digital sensor interface (XM3), and an interface for the main stage position transducer (XA), allowing for comprehensive connectivity and integration into various systems. The valve's integrated electronics provide sophisticated monitoring functions to detect errors such as undervoltage, communication errors, cable breaks, short circuits, microcontroller watchdog issues, and temperature extremes. These safety measures ensure reliable operation even in demanding environments. For ease of configuration and maintenance, the Bosch Rexroth 4WRLD27W600LJ-4X/MXY/24WD6T-151 can be managed using the IndraWorks DS PC program for project planning, parameterization, commissioning, diagnosis, and data management on Windows operating systems. Designed for versatility in hydraulic applications, this valve offers different pilot oil supply versions: external (XY), internal with external return (PY), internal supply with internal return (PT), or external supply with internal return (XT). Additionally, it boasts best-in-class hydraulic controller attributes with high response sensitivity and minimal hysteresis. The internal safety function conforms to category PL e according to EN ISO 13849-1 standards and meets CE conformity according to EMC Directive EU requirements.
