The Bosch Rexroth 4WS2EM10-5X/5B11ET315K31EV (R900785537) is a high-performance servo valve designed for precise control of position, force, and velocity in various applications. This valve is distinguished by its electromechanical converter torque motor, hydraulic amplifier with a nozzle-flapper plate system, and a control spool situated within a sleeve. The torque motor operates through an electrical input signal that induces a force via a permanent magnet on the armature, consequently generating torque that moves the flapper plate. This movement creates a pressure differential across the control spool, leading to the regulated flow between pressure and return flow ports. The sophisticated mechanical feedback system using a bending spring ensures the balance between feedback torque and electromagnetic torque of the motor, achieving zero pressure differential at the nozzle-flapper plate system when the desired position is reached. The servo valve's stroke and flow are proportionally controlled relative to the electrical input signal while considering the valve's pressure drop. This model incorporates integrated control electronics adjusted specifically for this valve type. These electronics are mounted on the cover cap of the torque motor and include an externally accessible potentiometer for zero-point adjustments. The WSEEDX series further includes electric spool position detection with an inductive transducer for enhanced dynamic performance and safety through mechanical feedback in case of electric supply failure. This Bosch Rexroth servo valve is engineered for subplate mounting with porting patterns according to ISO standards. It features dry control motor technology to prevent contamination from hydraulic fluid, wear-free control spool return elements, flow force compensation, centrically fixed control sleeves for reduced temperature and pressure sensitivity, gap-sealed pressure chambers to eliminate seal ring wear, and easily accessible external filters for maintenance. Please note that any adjustments to the zero point must be carried out by trained specialists to avoid potential damage to the system.
