Specifications
Supplier part number: 4WS2EM_10-5X-60B11E_
Name:Servo Valve For External Electronics (Rexroth - BOSCH). - 60 L/min , Valve Pressure Differential = 70 bar. - ET - Internal Supply , Internal Drain. - Two Stage , Type 4WS2E. - Nominal Size 10. - Connection Location to ISO 4401. - Code : 4401-05-0-094.
Description:Based on the official Rexroth technical documentation, your specified configuration for the 4WS2E servo valve is a standard variant. The 60 L/min nominal flow at a 70 bar valve pressure differential and ET (internal supply, internal drain) pilot oil setup is confirmed for the NG10 size . ✅ Confirmed Valve Specifications The table below summarizes the key parameters confirmed by the manufacturer's documentation . Parameter Specification Model Series 4WS2E – 2-stage directional servo valve for external electronics Nominal Size 10 (NG10) Nominal Flow (at 70 bar Δp) 60 L/min (±10% tolerance) Max. Operating Pressure 315 bar Pilot Oil Supply/Drain ET – Internal supply, internal drain (standard) Feedback Mechanical First Stage Type Nozzle/flapper plate amplifier Porting Pattern ISO 4401 Component Series 5X (Series 50 to 59) 🔧 Ordering Code Breakdown Based on the Rexroth ordering code structure, your specifications translate as follows : 4WS2E: Electrically operated 2-stage servo valve for external control electronics 10: Nominal size 10 (NG10) 5X: Component series 50 to 59 60: Nominal flow: 60 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) ET: Pilot oil supply: internal supply, internal 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 structured as: 4WS2EM10-5X/60B11ET315K31EV .
