Advantages of the Rexroth 4WSE2EM-6 Servo Valve

  • High precision & control — The servo valve uses a torque motor driving a nozzle-flapper amplifier, which then drives the main spool with mechanical feedback until equilibrium is achieved. This ensures that spool position (and thus flow/actuation) is proportional to the electrical command input.

  • Fast dynamic response — Because of the 2-stage construction and the design of the dry control motor, the valve is capable of high responsiveness and fine modulation of hydraulic flow/direction.

  • Reduced contamination risk & improved reliability — The dry torque motor prevents hydraulic fluid contamination of the solenoid gaps, which enhances reliability and durability in industrial hydraulic environments.

  • Integrated electronics version available — The “E” variant (4WSE2EM6) has integrated control electronics adjusted and tested for the valve, simplifying installation and setup by reducing the need for external amplifier modules.

  • Flexible mounting and subsystem compatibility — With porting per ISO 4401 and ability for 3-way or 4-way use (depending version), the valve can adapt to different hydraulic system layouts and applications.

  • Long service life and low maintenance — Features such as a wear-free control spool return element, accessible first-stage filters, and gap-sealed pressure chambers (reducing wear on seal rings) all contribute to lower maintenance and better longevity.
