The Bosch Rexroth 4WS2EM10-5X/30B11VH1ET210K31EV-100 (R901406233) is a highly sophisticated servo valve designed for precision control of position, force, and velocity in hydraulic systems. This valve features an electromechanical converter torque motor, a hydraulic amplifier with nozzle-flapper plate technology, and a control spool within a sleeve that is mechanically feedback-linked to the torque motor. The electrical input signal influences the torque motor coils, which in turn manipulate the flapper plate to create a pressure differential across the control spool. This differential adjusts the spool's position, controlling the connection between the pressure port and actuator ports, thereby regulating flow proportionally to the input signal.
The unit's mechanical feedback is facilitated by a bending spring that ensures equilibrium between feedback torque and electromagnetic torque from the motor. This balance maintains flow accuracy based on valve pressure drop. The servo valve requires external control electronics (WSEMX series) ordered separately or can utilize integrated control electronics (WSEEMX or WSEEDX series). These integrated electronics are tailored for this specific valve type and are mounted on the cover cap of the torque motor for convenient analog signal amplification.
Additionally, valves like WSEEDX series offer electric spool position detection and control for enhanced dynamics through electric feedback alongside mechanical feedback. Such redundancy ensures safe operation even during electrical supply failures by defaulting to zero range positioning.
It's essential to note that any adjustments to the valve's zero point should be conducted exclusively by trained professionals due to potential system damage risks. The 4WS2EM10-5X/30B11VH1ET210K31EV-100 promises durability with its wear-free return element and gap-sealed pressure chambers that mitigate seal ring wear. It also offers ease of maintenance with an externally accessible filter for its first-stage amplifier. This servo valve is designed for subplate mounting with porting patterns according to ISO standards and boasts an impressive maximum operating pressure of 315 bar along with a maximum flow rate of 100 l/min.
