The Bosch Rexroth 3WRCE 80 E001-1X/SG24/V (R901327004) is a high-response valve designed for precise control of flow rate and direction in closed-loop control circuits. This advanced valve system is composed of a pilot control valve featuring a low-friction nozzle flapper plate amplifier, mechanical feedback for spool position, a main control spool for regulating flow, and an inductive position transducer that is core-attached to the spool. It also includes integrated control electronics or can be configured to work with external electronics. The device operates by comparing command values with actual values, adjusting the torque motor of the pilot control valve accordingly to minimize control deviation. The main spool's stroke is proportional to the command value; however, it's important to note that flow is also influenced by pressure drop across the valve. In case of power failure, users should refer to the data sheet for preferred positioning as the spool may reach an undefined position. Factory-set opening points for spools L and V ensure optimal performance from the outset, but adjustments can be made post-installation if necessary. When replacing parts like the pilot control valve or control electronics, most settings should remain unchanged except for zero adjustments at the position transducer. The 3WRCE 80 E001-1X/SG24/V excels in applications requiring precise closed-loop or open-loop control of large flows. It's particularly suited for use in forging manipulators, pressing cylinders, and die casting machines. This model ensures robust performance and reliability in demanding industrial environments where precise hydraulic control is essential. Users are advised that this model is not intended for new applications and should consult Bosch Rexroth for alternatives with P and A exchanged configurations.
