Product Overview
The Rexroth 4WSE2EM6-22/5B8ET315K17EV (Material Number: R900972861) is a high-response, two-stage directional servo valve engineered for precision electrohydraulic control in demanding industrial applications. Manufactured by Bosch Rexroth, this valve utilizes a torque-motor pilot stage driving a spool-type main stage, delivering exceptional dynamic response and precise flow metering proportional to the electrical input signal. The 4WSE2EM6-22 series is designed for closed-loop position, velocity, and force control systems where accuracy, repeatability, and fast response are critical. With a nominal size of 6 and a rated flow capacity of 5 L/min at 315 bar, this servo valve serves as a vital control element in high-performance hydraulic systems requiring micron-level actuation precision.
