The Z4WE6E63-3X/EG24NK4 valve belongs to the Z4WE Solenoid Actuation Spool Valves series and is produced by Bosch Rexroth. It directs hydraulic flow in automated circuits where electrical control of spool position is required. The solenoid is powered by a nominal 24 V DC supply and draws a rated current of 1.25 A, establishing predictable magnetic force during every shift. Continuous energization is permitted because the unit consumes only 30 W while supporting a 100 percent duty cycle (S1). Connection is made through a DIN EN 175301-803 plug coded K4, simplifying field wiring tasks. Thermal limits are defined by a maximum coil surface temperature of 120 °C, and environmental sealing reaches IP65 to block dust and low-pressure water jets. When the coil is de-energized, switch-off transients may rise to 500 V, a factor that must be considered when selecting suppression devices.
The valve can be mounted in any position, giving designers flexibility when arranging manifolds and piping. Hydraulic ratings include a maximum operating pressure of 315 bar on service ports and a T-port back-pressure limit of 210 bar. It accommodates flow rates up to 50 l/min and permits as many as 15 000 direct-current actuations per hour. System oil cleanliness must meet ISO 4406 class 20/18/15 to maintain reliable performance. The interface follows the ISO 4401-03-02-0-05 porting pattern and fits bases machined to that standard. A calculated mean time to dangerous failure of 150 years highlights the long service expectancy of the component.
