The Bosch Rexroth 4WSE2EM10-5X/20B9ET315K31EV (R900946690) is a highly sophisticated electrically operated stage directional servo valve designed to precisely control position, force, and velocity in hydraulic systems. This valve features an electromechanical converter torque motor which, upon receiving an electrical input signal, generates a force that results in a torque. This torque then moves the flapper plate to create a pressure differential across the control spool. The movement of the spool regulates the connection between the pressure port and actuator ports, thus controlling fluid flow. The control spool's position is maintained through mechanical feedback via a bending spring until equilibrium is achieved between this feedback and the electromagnetic torque. The proportional relationship between the input signal and spool stroke allows for accurate flow control within the valve, although it should be noted that actual flow is also dependent on valve pressure drop. This Bosch Rexroth servo valve incorporates integrated control electronics adjusted specifically for its operation. These electronics are crucial for amplifying the analog input signal and ensuring precise actuation of the valve. An externally accessible potentiometer allows for zero-point adjustment but must be handled by trained specialists to avoid system damage. The 4WSE2EM10-5X/20B9ET315K31EV model boasts features such as a dry control motor that prevents contamination from hydraulic fluid, suitability for subplate mounting with porting patterns according to ISO standards, and wear-free control spool return elements. It also includes gap seals in pressure chambers for reduced wear on seal rings and an externally accessible filter for easy maintenance of the first-stage amplifier. The unit has been designed for maximum operating pressures up to bar and can handle maximum flows of l/min, making it suitable for various demanding applications where precision hydraulic control is vital.
