The Bosch Rexroth 4WSE2EM10-5X/10B9T315K31EV (R901219634) is a high-performance stage directional servo valve designed for precision control of position, force, and velocity in hydraulic systems. This valve is characterized by its electromechanical converter torque motor, hydraulic amplifier with a nozzle flapper plate system, and a control spool within a sleeve. The torque motor is activated by an electrical input signal, which generates a force that translates into the movement of the flapper plate. This movement creates a pressure differential across the control spool, leading to the adjustment of flow between pressure ports and actuator ports. The control spool's position is finely tuned through mechanical feedback via a bending spring until it balances with the electromagnetic torque from the torque motor. This balance ensures precise flow control proportional to the electrical input signal. The servo valve's performance can be influenced by its pressure drop across the valve. Designed for subplate mounting and compliant with ISO porting patterns, this Bosch Rexroth valve features dry control motor technology to prevent contamination from hydraulic fluid and can operate as both 3-way or 4-way versions depending on application needs. It incorporates wear-free elements such as a control spool return element and has external or integrated electronics options for controlling its functions. The integrated control electronics are specifically calibrated for this valve type, offering easy zero-point adjustment through an externally accessible potentiometer. Additionally, certain models like WSEEDX... include electric spool position detection for enhanced dynamic performance through electric feedback, while still maintaining mechanical feedback to ensure functionality in case of power loss. This servo valve boasts robust specifications with a maximum operating pressure of up to bar and maximum flow rates reaching l/min. It also features design considerations such as flow force compensation, centrically fixed control sleeves for reduced temperature and pressure susceptibility, gap-sealed pressure chambers at the control sleeve to minimize wear on seal rings, and an externally accessible filter for easy maintenance of its first-stage components.
