Based on the search results, the Rexroth 4WS2E is a two-stage, 4-way directional servo valve designed for use with external electronics.Here is a summary of its key specifications and characteristics that match your request:✅ Confirmed Product SpecificationsParameter Specification Source(s)Model Series 4WS.2E (Two-stage servo valve) Nominal Size NG6 (Size 6) Valve Type 4-way, mechanical feedback Pilot Stage Nozzle/flapper plate amplifier Max. Operating Pressure 315 bar Porting Pattern ISO 4401-03-02-0-05 (CETOP 3) Nominal Flow 2 ... 25 L/min (at 70 bar differential) The 2 L/min flow rate you specified at a 70 bar valve pressure differential is a standard nominal flow option for this valve series.🔧 Design & Operation FeaturesThe valve is a two-stage unit that combines a torque motor with a hydraulic amplifier. Key design features include:A dry torque motor that separates the electrical coil from the hydraulic fluid to prevent contamination.A nozzle/flapper plate as the first hydraulic stage, which converts the electrical signal from the torque motor into a pressure differential.A spool with mechanical feedback, which provides a direct, wear-free connection to the feedback element.📋 Valve Series and Application ContextThe 4WS.2E series is also available in sizes NG10 and NG16, with maximum flows up to 200 L/min. It is used for applications requiring precise closed-loop control of position, force, or velocity.
