The Bosch Rexroth 2WRC 50 K001-1X/E/M (R900957434) is a high-response stage valve designed for precise control of flow rate and direction in closed loop control circuits. This advanced hydraulic component consists of a pilot control valve with a servo directional valve pilot, featuring a dry torque motor and low-friction jet flapper amplifier. It also includes mechanical feedback for spool position, a main control spool for managing flow, an inductive position transducer linked to the spool, and integrated control electronics specifically for the WRCE model. The valve's functionality is centered around its ability to compare command and actual values within the integrated electronics, adjusting the pilot control valve solenoids proportionally to minimize system deviation. The main spool's stroke is thus finely tuned in response to command inputs, although flow is also influenced by pressure drop across the valve. Valve features include bidirectional flow capabilities and leak-free closure at low command values due to the closed loop control circuit actively correcting spool position. The valve ensures rapid switching times within its operational range but may experience delays when responding to sudden jumps from closed to small opening values. An important aspect of maintenance is that only the filter element on the pilot control valve can be replaced without needing further adjustments, except zero calibration at the position transducer. The 2WRC 50 K001-1X/E/M has been engineered with specific attention to details such as factory preset opening points and minimum recommended control pressures derived from system requirements. It must be noted that power loss leads to an undefined spool position, emphasizing the importance of stable power supply for proper operation. Finally, this Rexroth valve finds its applications in systems requiring precise flow management like forging manipulators, pressing cylinders, and die casting machines. Its block installation design and option for external or integrated electronics make it versatile for different setups while ensuring optimal performance in demanding hydraulic tasks.
