Product Overview
The Rexroth 4WSE2EM6-22/10B9ET315K17EV (Material Number: R900952166) is a high-response, two-stage directional servo valve engineered for precision electrohydraulic control in demanding industrial applications. Manufactured by Bosch Rexroth, this valve features a torque-motor-driven pilot stage with a mechanical feedback mechanism that positions the main spool proportionally to the electrical input signal. The result is exceptionally fast dynamic response, high resolution, and precise directional and flow control of hydraulic actuators. With a nominal flow capacity of 10 L/min at a pressure differential of 35 bar per land, this servo valve is ideally suited for closed-loop position, velocity, and force control systems where accuracy and repeatability are critical.
