The Bosch Rexroth 4WSE2ED10-5X/45B9ET315K31EV-102 (R901037413) is an advanced stage directional servo valve designed for precision control of position, force, and velocity in hydraulic systems. This particular model features a robust electromechanical converter torque motor, a hydraulic amplifier based on the nozzle-flapper plate principle, and a control spool within a sleeve. The torque motor operates through an electrical input signal that generates force using a permanent magnet, producing a torque which moves the flapper plate and creates a pressure differential across the control spool. This action connects the pressure port to an actuator port while simultaneously linking another actuator port to the return flow. Incorporated into this valve's design is a mechanical feedback system consisting of a bending spring that balances the electromagnetic torque with feedback torque, ensuring precise control of the spool position and flow rate proportional to the electrical input signal. The flow capacity of this servo valve is contingent upon the pressure drop across it. This model includes integrated control electronics specially calibrated for this type of valve. These electronics are mounted on the cover cap of the torque motor, facilitating easy adjustment of the valve's zero point through an externally accessible potentiometer. Additionally, some variants like WSEEDX... offer electric spool position detection with inductive transducers for enhanced dynamic performance and reliability. The 4WSE2ED10-5X/45B9ET315K31EV-102 servo valve boasts features like dry control motors that prevent contamination from hydraulic fluid, suitability for subplate mounting with ISO standard porting patterns, wear-free control spool return elements, and externally accessible filters for easy maintenance. It emphasizes reliability with its temperature and pressure-resistant design including gap-sealed pressure chambers at the control sleeve. As with all precision components, any adjustments to its zero point must be carried out by trained specialists to avoid potential system damage.
