The Z4WE6E68-30/EW110K4QMAG24 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is used to route pressurized fluid to cylinders or motors in hydraulic automation. Its nominal size of 6 suits compact manifolds while maintaining adequate passage for flow. The porting pattern complies with ISO 4401-03-02-0-05 so it matches standard subplates without adapter blocks. A maximum flow capacity of 60 l/min defines the throughput the valve can handle, and an operating pressure limit of 350 bar at ports P, A, and B allows operation in high-pressure circuits. The solenoid coil works on 110 V AC at 50 or 60 Hz, with a voltage tolerance of ±10 % to accommodate supply variations. During actuation the coil draws 220 VA to shift the spool, after which it holds position at 50 VA to reduce heat. Continuous energization is permissible because the duty cycle is specified at 100 % ED.
Installation is unrestricted, as the valve can be mounted in any position without affecting performance. When fitted with a proper mating connector, the assembly achieves IP65 ingress protection, preventing dust and low-pressure water exposure from reaching the electrical parts. The K4 connector in accordance with DIN EN 175301-803 offers a standardized plug for straightforward wiring. Insulation class H materials inside the coil tolerate the temperatures generated during sustained operation. The design supports a switching frequency of up to two cycles per second, enabling responsive directional control. Return-line pressure must stay below 160 bar at the tank port to protect seals and housing. Hydraulic fluid cleanliness is limited to ISO 4406 class 20/18/15 to preserve spool and bore accuracy. These combined features result in stable service within automated hydraulic systems.
