Rexroth R900243941 4WS2EM10-51/75B11ET315K31DV Hydraulic Servo Valve
Rexroth R900243941 (4WS2EM10-51/75B11ET315K31DV) professional 4-way servo valve direct actuation It uses a nozzle-flapper pilot stage and mechanical feedback for superb accuracy. It incorporates an internal pilot oil supply and return, which makes this particular model a good choice for tight system designs where external plumbing needs to be kept to a minimum. It remains a gold standard for automation in maritime, aerospace and heavy industrial applications, built to endure high pressure.
Bosch Rexroth 4WS2EM10 Servo Valve The 4WS2EM10 is a 2-stage directional control valve with excellent precision for the most demanding industrial applications. Optimize your hydraulic control systems. This unit provides accurate control of location, force, pressure and velocity for enhanced response in closed loop applications.
Main Features
- Robust Design: High quality construction for ongoing reliability with operating pressures up to 315 bar.
- Mechanical Feedback: The established 2-stage flapper-nozzle design assures consistent, repeatable motion control.
- Industrial Standard Mounting: ISO 4401-05-05-0-05 interface designs for easy installation into existing manifolds.
- FKM Seal Compatibility Viton (FKM) seals make the valve chemically compatible with a wide range of mineral-based hydraulic fluids (HL/HLP/HVLP).

Our Engineer’s Guide:
- Cleanliness Is Key. Servo valves are quite susceptible to contaminations. Maintain your hydraulic fluid in the recommended cleanliness class (ISO 4406 18/16/13 or greater). Use good grade inline filtration to prevent pluggage of the flapper-nozzle orifice.
- Pressure from Pilots. Keep your pilot oil supply steady. At startup , check the pilot stage pressure to be at least 10 bar so that the spool is shifted properly to the location you want.
- Tuning the electricity. This model is based on offboard electronics, therefore be sure to tune your servo-amplifier correctly for the specific coil resistance (85 $\Omega$) to minimize thermal drift or sluggish response times.
