Specifications
Supplier part number: 4WS2EM_6-2X-5B11ET2_
Name:Servo Valve For External Electronics (Rexroth - BOSCH). - 5 L/min , Valve Pressure Differential = 70 bar. - Two Stage , Type 4WS2E. - Nominal Size 6. - Connection Location to ISO 4401. - Code : 4401-03-02-094.
Description:The Bosch Rexroth 4WS2E servo valve is a two-stage, 4-way directional valve designed for high-precision closed-loop control applications like position, force, and speed control . It is operated by external electronics (servo amplifier) which are ordered separately . The 5 L/min nominal flow rate you specified is a standard option for this valve when measured at the 70 bar valve pressure differential (35 bar per control edge) . The NG6 (Nominal Size 6) version conforms to the ISO 4401-03-02-0-05 porting pattern . ✅ Technical Specifications Parameter Specification Source(s) Model Series 4WS2E (Two-stage servo valve) Nominal Size 6 (NG6 / CETOP 3) Maximum Operating Pressure 315 bar Nominal Flow (at 70 bar Δp) 5 L/min (±10% tolerance) Porting Pattern ISO 4401-03-02-0-05 🔧 Ordering Code Structure The Rexroth ordering code for your specific valve follows this structure : 4WS2E: Electrically operated 2-stage servo valve for external control electronics . 6: Nominal size 6 . 2X: Component series 20 to 29 (unchanged installation dimensions) . 5: Nominal flow of 5 L/min at 70 bar . ...: Additional codes for spool overlap, seal material, and other options . A complete order code example for a 5 L/min valve is 4WS2EM6-2X/5B12ET210K17EV .
