The 4WRP10W32S-1X/G24Z4/M-787 solenoid valve belongs to the 4WRP Solenoid Valves series and is manufactured by Bosch Rexroth for hydraulic automation where electrical control of oil flow is required. The coil resistance is 2.5 Ω, which sets the current demand when the 24 V DC supply is applied. Under this voltage the solenoid can draw up to 3.7 A while power consumption remains below 60 VA, letting typical machine controllers power the unit directly. A 100 % duty cycle permits continuous energization without forced cooling. Command steps are followed within 50 ms, providing fast loop response. The progressive flow characteristic supports fine metering at small spool strokes and higher delivery at larger strokes, and hysteresis is held to 0.75 % to keep position repeatability tight.
The valve provides a nominal flow of 32 l/min at a 5 bar pressure drop per notch, giving designers a clear throughput reference. Ports p, a, and b accept working pressures up to 315 bar, the t port withstands 250 bar, and the l port is limited to 2 bar, so return and leakage lines can be sized correctly. The mounting interface follows ISO 4401-05-06-0-94 in NG10 size, allowing direct installation on standard subplates. An IP65 protection rating shields the enclosure against dust and water jets when the DIN 43650 / ISO 4400 connector with M16×1.5 thread is fitted. The complete assembly weighs 8.0 kg, a factor that influences support structure and vibration considerations.
