The Z4WE6E63-3X/EG24K4QMBG24 is produced by Bosch Rexroth for the Z4WE Solenoid Actuation Spool Valves series and directs hydraulic flow in automated equipment. It handles operating pressures up to 315 bar at ports P, A, and B, permitting use in high-pressure circuits. A maximum flow of 50 l/min defines the peak volume it can transmit without excessive pressure loss. The housing follows porting pattern ISO 4401-03-02-0-05, so it fits standard subplates. Continuous energization is allowed because the coil is rated for a 100 percent duty cycle. Operation requires a 24 V DC supply, and at that voltage the coil draws 1.25 A, resulting in 30 W of power consumption. An IP65 protection class shields the assembly from dust and water jets when the mating connector seal is fitted.
Electrical connection is through a DIN EN 175301-803 3-pin plus PE plug that provides straightforward wiring and protective earth. The coil tolerates ±10 percent voltage variation, maintaining reliable actuation during supply fluctuations. Surface temperature may reach 120 °C under continuous load, a limit that guides thermal spacing. When de-energized, up to 500 V of switch-off overvoltage can appear, so suppression devices must be chosen accordingly. The unit can switch as many as 15 000 cycles per hour, supporting rapid directional control. Hydraulic fluid cleanliness must meet ISO 4406 class 20/18/15 to minimize spool wear. Port T withstands return pressures up to 210 bar, enabling operation in circuits with elevated back-pressure. A mean time to dangerous failure of 150 years indicates very low safety-related risk during its service life.
