The Bosch Rexroth 4WS2EM10-5X/10B11ET315K31EV (R900956128) is an advanced stage directional servo valve designed for precision control of position, force, and velocity in hydraulic systems. This electrically operated valve features an electromechanical converter torque motor, a nozzle flapper plate hydraulic amplifier, and a control spool within a sleeve. The torque motor operates through an electrical input signal that generates force via a permanent magnet acting on the armature. This movement then translates into a torque that shifts the flapper plate from its central position, creating a pressure differential across the control spool. The valve's unique construction includes mechanical feedback via a bending spring connected to the control spool and flapper plate or torque motor. The feedback mechanism ensures that the electromagnetic torque is balanced with the feedback torque, stabilizing the pressure differential at zero. As a result, the stroke of the control spool—and thus the flow of the servo valve—is proportionally controlled relative to the electrical input signal, although it is also influenced by valve pressure drop conditions. This Bosch Rexroth model incorporates integrated control electronics adjusted specifically for this type of valve. These electronics are mounted on the cover cap of the torque motor and include an externally accessible potentiometer for zero-point adjustment. For systems requiring higher dynamics and precision, this model also provides electric spool position detection and control through an inductive position transducer integrated within. Designed for subplate mounting with porting patterns according to ISO standards, this servo valve ensures clean operation with its dry control motor that prevents contamination by hydraulic fluid. It can be utilized as both 3-way and 4-way versions due to its versatile design. The robust construction includes wear-free return elements for the control spool and gap-sealed pressure chambers at the control sleeve for enhanced durability. Additionally, it features an externally accessible filter for maintenance ease. With component series X capabilities, this Bosch Rexroth servo valve can handle maximum operating pressures up to bar and maximum flow rates up to l/min, ensuring reliable performance across various applications while maintaining precise control over hydraulic system parameters.
