The Z4WE6E146-3X/EG24N9K4 is a solenoid-actuated spool valve from Bosch Rexroth in the Z4WE Solenoid Actuation Spool Valves series, intended for directional control in hydraulic automation circuits. It installs as a size 6 unit on subplates that follow the ISO 4401-03-02-0-05 porting pattern, so interchange with other modular components is straightforward. A nominal supply of 24 V DC drives the coil at 1.25 A, and the circuit can tolerate voltage variation of ±10 % without malfunction. Electrical power draw remains fixed at 30 W in direct-current service, while a duty cycle of 100 % ED permits the coil to stay energized continuously. Thermal limits are defined by a maximum coil surface temperature of 120 °C, allowing use in warm manifolds. These electrical features combine to provide reliable actuation of the directional element under constant load.
An IP65 housing protects the assembly against dust and low-pressure water jets, and wiring is made through a DIN EN 175301-803 plug that carries the K4 coding. Operators can shift the spool mechanically with a concealed manual override marked N9 when commissioning or debugging systems. Hydraulic ratings include a maximum flow of 50 l/min and a working pressure of 315 bar on ports P, A, and B; the tank port withstands 210 bar in direct-current operation. The valve changes state up to 15 000 times per hour, supporting rapid cycling applications that demand high throughput. Fluid entering the unit must meet ISO 4406 class 20/18/15 cleanliness to avoid wear or sticking.
