Z4WE6X163-3X/EG24K4SO60

The Z4WE6X163-3X/EG24K4SO60 valve belongs to the Z4WE Solenoid Actuation Spool Valves series and is manufactured by Bosch Rexroth for directional control in hydraulic automation. It operates on a nominal voltage of 24 V DC so that mobile or stationary power supplies can drive the solenoid without conversion. A rated coil current of 1.25 A is required to generate the magnetic force needed to shift the spool. The coil draws 30 W, which helps designers size power supplies and manage heat within the manifold block. Continuous operation is permitted because the duty cycle is 100 % ED, eliminating pauses for cooling during sustained actuation. Wiring is accomplished through a DIN EN 175301-803 connector, simplifying interchange with other industrial coils. The circuit can tolerate voltage variations of ±10 %, reducing sensitivity to supply fluctuations in the field. An IP65 protection class shields the coil from dust and water jets, allowing installation in exposed machine areas. Mounting follows the ISO 4401-03-02-0-05 porting pattern so the valve fits standard CETOP 03 subplates.

The pressure ports P, A, and B are rated for 315 bar, enabling the valve to control high-pressure circuits without leakage. Return port T withstands 210 bar in direct current service, providing a safety margin for back-pressure events. A maximum flow of 50 l/min allows the spool to pass sufficient oil for medium-size actuators. Flow paths P–A/B and A/B–T share an orifice size of 2.0 mm, defining the conductance and response time of the metering edges. The coil surface may reach 120 °C, so surrounding components must be selected for that thermal environment. Up to 15 000 switching cycles per hour are permitted, which supports rapid cycling duties in servo-controlled systems. Switch-off transients are limited to 500 V, helping protect driver electronics from inductive voltage spikes. A mean time to dangerous failure of 150 years reflects the reliability expected in safety-related machinery.
