The 4WRP10EA32S-1X/G24Z4/M valve belongs to the 4WRP Solenoid Valves series from Bosch Rexroth. It regulates proportional flow in hydraulic automation circuits through an NG10 (ISO 4401-05-06-0-94) mounting interface that matches common subplates. The coil is specified for 24 V DC and has a resistance of 2.5 Ω at 20 °C so the drive electronics can predict current draw accurately. During full actuation the solenoid can accept up to 3.7 A and 60 VA, enabling steady spool positioning within the 50 ms maximum response time for a 100 % command step. Maximum hysteresis is limited to 0.75 %, while the range of inversion stays within 0.5 %, both of which contribute to repeatable metering. At a pressure drop of 5 bar per notch the valve delivers a nominal flow of 32 l/min, allowing precise control of medium-size actuator speeds.
The housing carries an IP65 rating to shield internal components from dust and water jets, and wiring is made through a DIN 43560-AM2 connector that fits standard field cabling. Internal leakage is capped at 80 cm³/min per edge at a 100 bar differential, minimizing energy losses in closed-center circuits. The pressure limits reach 315 bar at ports P, A, and B, while the tank port tolerates up to 250 bar and port L is restricted to 2 bar, so circuit designers can size lines and accumulators correctly. Overall weight is 8.0 kg, providing sufficient mass for vibration damping without complicating manifold installation.
