The Bosch Rexroth 4WSE2EM10-5X/5B9ET315K31EV (R901006218) is an advanced stage directional servo valve designed to accurately control position, force, and velocity in hydraulic systems. This servo valve features a precision-engineered electromechanical converter torque motor, a hydraulic amplifier based on the nozzle-flapper plate principle, and a control spool housed within a sleeve. The torque motor responds to electrical input signals by generating a force through a permanent magnet that acts upon an armature, resulting in the movement of the flapper plate and subsequent pressure differential across the control spool. This pressure differential adjusts the spool's position, effectively managing the connection between the pressure port and actuator ports. Mechanical feedback is provided via a bending spring that links the flapper plate to the control spool, ensuring equilibrium between electromagnetic torque and feedback torque. The servo valve's flow is proportionally controlled relative to the electrical input signal while taking into account the valve's pressure drop. The 4WSE2EM10-5X/5B9ET315K31EV comes exclusively with integrated control electronics tailored for this specific model, negating the need for external control electronics. These integrated electronics facilitate analog signal amplification directly within the unit and feature an externally accessible potentiometer for zero-point adjustments. Additionally, this valve type includes electric spool position detection and control for enhanced dynamics through electric controller amplification in small signal ranges while maintaining mechanical feedback as a failsafe. Constructed with durability in mind, it features dry control motors to prevent contamination from hydraulic fluid and wear-free elements for reliable long-term operation. Its design allows subplate mounting according to ISO standards with easily accessible filters for maintenance. It should be noted that adjustments to the zero point must be carried out by trained specialists to avoid potential system damage. The 4WSE2EM10-5X/5B9ET315K31EV represents Bosch Rexroth's commitment to precision engineering in hydraulic servo valves, offering robust performance for sophisticated industrial applications.
