The Z4WEH22E63-5X/6EG24N9DK23L valve belongs to the Z4WE Solenoid Actuation Spool Valves series and is manufactured by Bosch Rexroth for directional control in hydraulic automation systems. It relies on electro-hydraulic actuation so a 24 VDC solenoid drives a pilot stage that shifts the main spool. Spool symbol E63 defines the land configuration used to open and close flow paths. A maximum flow capacity of 650 l/min allows the unit to handle high-volume circuits, while a 315 bar operating pressure rating supports heavy-duty machinery. The design provides four working ports for connection to pressure, tank, and actuator lines. Fluid interfaces follow the ISO 4401-08-08-0-05 porting pattern for compatibility with standard subplates. Electrical termination is achieved through a Brad Harrison Mini-Change three-pole plug with an integrated LED, and the connector meets the ANSI/B93.55M-1981 standard.
The valve body corresponds to CETOP size D08, and the NFPA T3.5.1 R2-2002 D08 mounting pattern lets it bolt directly to manifold stacks. Pilot oil must be supplied externally so control pressure remains stable regardless of main line fluctuations, and the pilot flow is returned externally to avoid back-pressure in the control chamber. A concealed manual override permits manual shifting during setup or power loss without exposing components to contaminants. NBR seals are fitted to contain mineral hydraulic fluids and maintain leakage control across temperature changes. The complete assembly weighs 21.1 kg and requires rigid support when mounted in equipment.
