Supplier part number: 4WS2EM_10-5X-75B11-_
Name:Servo Valve For External Electronics (Rexroth - BOSCH). - 75 L/min , Valve Pressure Differential = 70 bar. - External Supply , External Drain. - Two Stage , Type 4WS2E. - Nominal Size 10. - Connection Location to ISO 4401. - Code : 4401-05-0-094.
Description:The Rexroth 4WS2E two-stage servo valve for external electronics is confirmed to have a 75 L/min nominal flow at a 70 bar valve pressure differential, and this is a standard configuration for the NG10 size. ✅ Confirmed Valve Specifications Parameter Specification Source(s) Model Series 4WS2E – 2-stage directional servo valve for external electronics Nominal Size 10 (NG10) Nominal Flow (at 70 bar Δp) 75 L/min (±10% tolerance) Max. Operating Pressure 315 bar Pilot Oil Supply/Drain – – External supply, external drain Feedback Mechanical First Stage Type Nozzle/flapper plate amplifier Porting Pattern ISO 4401 🔧 Ordering Code Breakdown Your specifications translate into the following ordering code structure. The – symbol in the code denotes the external supply, external drain configuration: 4WS2E: Electrically operated 2-stage servo valve for external control electronics 10: Nominal size 10 (NG10) 5X: Component series 50 to 59 (installation dimensions unchanged) 75: Nominal flow: 75 L/min at 70 bar valve pressure differential B: Valve version code (e.g., spool overlap) 11: Coil number for external electronics (30 mA / 85 Ω per coil) –: Pilot oil supply: external supply, external drain 315: Inlet pressure range to 1st stage: 10 to 315 bar K31: Electrical connection code A complete order code example for your configuration would be: 4WS2EM10-5X/75B11-315K31EV.
