The Bosch Rexroth 4WS2EM10-5X/30B11T315K31EV-100 (R901190354) is an advanced stage directional servo valve designed for precision control of position, force, and velocity in hydraulic systems. This valve integrates a torque motor with an electromechanical converter, a hydraulic amplifier based on the nozzle-flapper plate principle, and a control spool within a sleeve. The torque motor responds to electrical input signals by generating a force through its permanent magnet and armature assembly, resulting in a torque that moves the flapper plate. This movement creates a pressure differential across the control spool, which then adjusts its position to regulate the connection between pressure and actuator ports for precise fluid flow control. The 4WS2EM10-5X/30B11T315K31EV-100 features mechanical feedback via a bending spring that balances the electromagnetic torque with the position of the control spool until equilibrium is achieved. The servo valve's flow is proportional to the electrical input signal but also depends on the valve's pressure drop. This Bosch Rexroth servo valve is equipped with integrated control electronics specifically tailored for this model. These electronics amplify analog input signals to ensure accurate actuation of the valve. Additionally, it comes with an externally accessible potentiometer for zero-point adjustments. The WSEEDX variant includes electric spool position detection and control for enhanced dynamics and reliability, even if electric power supply fails. Constructed for durability and precision, this servo valve features wear-free components such as its control spool return element and gap-sealed pressure chambers at the control sleeve. It is designed for subplate mounting conforming to ISO standards and boasts an easily accessible filter for maintenance purposes. Users should note that any adjustments to the zero point must be conducted by trained specialists to avoid potential system damage.
