The Bosch Rexroth 2WRCE 80 K001-1X/SG15/M-23 (R900578398) is a high-response stage valve designed for precise flow and direction control in closed loop control circuits. This advanced valve system is comprised of a pilot control valve with a dry torque motor, low friction jet flapper amplifier, mechanical feedback for spool position, a main control spool for managing flow, and an inductive position transducer linked to the spool of the third stage. It also features integrated control electronics specifically for the WRCE model. The valve's functionality hinges on its ability to compare command and actual values within its integrated electronics, controlling the pilot valve solenoids proportionally to any deviations in the closed loop control. The main spool's stroke is regulated in accordance with command values, though it's important to note that flow is also influenced by pressure drop across the valve. Key features of this valve include bidirectional flow through ports A and B, leak-free closure at low command values due to precise spool positioning, and factory-set opening points that can be calibrated if necessary. Despite different diameters in the seat area leading to unbalanced pressures, this can be compensated by ensuring appropriate control pressure is maintained. The 2WRCE 80 K001-1X/SG15/M-23 valve is particularly suitable for applications requiring fast response times and accurate positioning such as forging manipulators, pressing cylinders, and die casting machines. Its block installation design allows for ease of integration into various hydraulic systems. Users should note that loss of power may result in an undefined spool position and that port B should preferably be connected to the actuator for optimal performance.
