The 4WRL10V70P-3X/G24ETZ4/M valve is produced by Bosch Rexroth and belongs to the 4WRL Solenoid Valves series. It regulates hydraulic flow and pressure in automated circuits. The unit uses a 4/3-way spool denoted V to direct actuator ports in both directions. It mounts on an ISO 4401-05-05-0-94 interface, allowing installation on standard subplates. A nominal flow of 70 l/min is obtained at a 10 bar differential, and the P non-linear flow characteristic permits fine metering near the center position. Working lines p, a, and b can withstand 350 bar, while the t, x, and y ports tolerate 250 bar. Stable operation requires at least 10 bar of control oil pressure. The solenoid is powered from a 24 V DC supply and can draw up to 2.7 A under full excitation.
Internal piloting simplifies piping because the pilot oil supply is taken from port E and the return flows to port T. The coil resistance is 2.5 Ω at 20 °C, which limits current surge and heat rise. A plug conforming to DIN 43560-AM2 (Z4) provides the electrical connection and secures the leads against vibration. When this connector is sealed, the enclosure attains an IP65 protection class that blocks dust and water jets. The valve switches fully in 25 ms at 100 bar, supporting precise closed-loop control. NBR seals, indicated by the M code, are compatible with common hydraulic fluids and maintain elasticity over the normal service temperature range.
