Specifications
Supplier part number: 4WS2EM_10-5X-45B11T_
Name:Servo Valve For External Electronics (Rexroth - BOSCH). - 45 L/min , Valve Pressure Differential = 70 bar. - T - External Supply , Internal Drain. - Two Stage , Type 4WS2E. - Nominal Size 10. - Connection Location to ISO 4401. - Code : 4401-04-0-094.
Description:For your Bosch Rexroth 4WS2E servo valve, the 45 L/min flow rate at a 70 bar differential with external supply and internal drain is a standard configuration. The "T" designation for the pilot oil supply is confirmed by the manufacturer's ordering code . The valve is a two-stage type designed for external electronics, and the NG10 version uses the ISO 4401-05 porting pattern . 📊 Confirmed Valve Specifications Parameter Specification Source Model Series 4WS2E Nominal Size 10 (NG10) Nominal Flow (at 70 bar Δp) 45 L/min (±10% tolerance) Max. Operating Pressure 315 bar Pilot Oil Supply/Drain T – External supply, internal drain 🔧 Ordering Code Breakdown Your specifications translate into the following Rexroth ordering code structure. This is confirmed by examples of this specific valve model : 4WS2E: Electrically operated 2-stage servo valve for external control electronics . 10: Nominal size 10 (NG10) . 5X: Component series 50 to 59 . 45: Nominal flow: 45 L/min at 70 bar valve pressure differential . B: Valve version code . 11: Coil number for external electronics (30 mA / 85 Ω per coil) . T: Pilot oil supply: external supply, internal drain . 315: Inlet pressure range to 1st stage: up to 315 bar . K31: Electrical connection code . A complete order code example for your configuration would be structured as: 4WS2EM10-5X/45B11T315K31CV .
