The Z4WH10E63-4X/ valve is part of the Z4WE Solenoid Actuation Spool Valves series produced by Bosch Rexroth for directional control in hydraulic automation. It uses hydraulic actuation to move the E63 spool between two switching positions so flow is either directed or blocked according to the circuit logic. A nominal size 10 body accommodates a maximum flow of 160 l/min, while a pilot-operated mechanism receives control pressure through an external pilot oil supply. The sandwich plate connection follows the ISO 4401-05-04-0-05 mounting pattern and matches the NFPA D05 porting, allowing stacking with compatible subplates. Four working ports are provided in the housing to interface with adjacent modules.
The valve accepts HL, HLP, or HETG hydraulic fluids and is designed for continuous service at pressures up to 315 bar. Pilot oil returns externally, avoiding internal pressure buildup and contributing to consistent spool movement. NBR seals contain the selected fluid without leakage at the stated pressure limit, and the complete assembly weighs 3.58 kg, enabling manual installation into manifold stacks. These remaining attributes complement the interface and flow ratings described earlier and define the operating envelope required for precise hydraulic automation tasks.
