The Bosch Rexroth 4WS2EM10-5X/5B11VH1T210K31EV-100 (R901272157) is a high-performance electrically operated servo valve designed to precisely control position, force, and velocity in various applications. This advanced valve features an electromechanical converter torque motor, hydraulic amplifier with a nozzle flapper plate system, and a control spool within a sleeve for reliable operation. The torque motor responds to electrical input signals, creating a force that moves the flapper plate and generates a pressure differential across the control spool. This movement adjusts the connection between the pressure port and actuator ports, enabling precise fluid flow control proportional to the input signal. The valve's mechanical feedback is facilitated by a bending spring connecting the control spool to the flapper plate or torque motor. The balance between feedback torque and electromagnetic torque ensures stable operation until zero pressure differential is achieved at the nozzle flapper plate system. The integrated electronics in this model include special control electronics that amplify the analog input signal for accurate valve actuation. An externally accessible potentiometer allows for zero-point adjustments. This Bosch Rexroth servo valve also boasts features such as wear-free control spool return elements, gap-sealed pressure chambers to prevent seal ring wear, and an external filter for easy maintenance of the first stage. Designed for subplate mounting with porting patterns according to ISO standards, it offers dry control motor operation preventing contamination of solenoid gaps by hydraulic fluid. The unit is engineered for maximum operating pressures up to 315 bar and can handle flow rates up to 100 liters per minute. It should be noted that any adjustments to the valve's zero point must be performed by trained specialists due to potential system damage risks.
