The Bosch Rexroth 3WRCE40V000X-2X/SG24K31/C5M-140 (R901216798) is a stage high-response valve designed for precision control of flow quantity and direction within control loops. This product features a robust setup that includes a stage pilot control valve with a dry torque motor, low-friction nozzle flapper plate amplifier, mechanical feedback of the spool position, a main stage for flow control, an inductive position transducer attached to the spool's core, and integrated control electronics. The function of this valve is to ensure precise regulation of the main spool stroke proportionally to command values while considering the valve pressure drop. The integrated or external electronics manage the comparison between command and actual values, actuating the torque motor of the pilot control valve in response to any control deviation. Consequently, this controls the flow into and out of chambers A and B, which in turn actuate the main spool through a closed-loop system. Valve particularities include factory-set opening points for the V spool which can be readjusted using zero adjustment potentiometer R after replacement of components. During maintenance, no settings need adjustments except for this zero point at the position transducer. The pilot control valve is designed to ensure safety by connecting pilot pressure to chamber B during power failures, thereby opening from A to T or closing P to A. This high-response valve is intended for block installation design and is suitable for various applications such as presses, die casting machines, and nibbling axes. It excels in tasks requiring precise position, pressure, force, and velocity control. The integrated electronics OBE compensate for any trimming discrepancies in the pilot valve ensuring consistent performance.
