The 4WE6E19B6X/EG24N9K4K/62SO43A-1042 directional spool valve is built by Bosch Rexroth within the WE Directional Spool Valves series. Designed to switch hydraulic flow between ports, it supports machine automation circuits that require compact, electrically actuated control. The nominal size is 6, defining passage dimensions compatible with ISO subplates of similar rating. A maximum flow of 80 l/min allows the valve to handle medium-capacity actuators without excessive pressure loss. The pressure limit on the pressure, A, and B ports is 350 bar so the unit can work in high-pressure supply lines, while the T port is limited to 210 bar to protect the tank return path. Solenoid actuation is powered from a 24 V DC supply, and a nominal power draw of 30 W sets the demand on the control cabinet. Continuous service is possible because the coil is rated for a 100 % duty cycle, avoiding the need for rest periods during repetitive switching.

For thermal endurance, the coil surface is allowed to reach 120 °C, which defines permissible ambient temperature and cooling requirements. The rectangular K4K electrical connector gives quick wiring and carries an IP65 rating, preventing dust and low-pressure water ingress when a proper mating plug is used. A concealed N9 manual override is provided so technicians can shift the spool during commissioning without energizing the coil. The /62 locating hole with a locking pin helps position the body accurately on the manifold and resists shifting under vibration. Mounting follows the ISO 4401-03-02-0-05 interface, ensuring interchangeability with standard CETOP 03 subplates. System cleanliness must meet ISO 4406 class 20/18/15, limiting particle contamination that could score the spool lands. The assembly with two solenoids weighs 1.95 kg, making installation manageable without lifting equipment. These characteristics support reliable, leak-tight switching in aggressive mobile and industrial hydraulic environments.
