The Z4WE6E53-3X/EG24N9K4 valve is manufactured by Bosch Rexroth within the Z4WE Solenoid Actuation Spool Valves series. It switches hydraulic oil paths in automated machinery where rapid on-off control is needed. The valve withstands 315 bar at P, A, and B ports, while the tank port is limited to 210 bar, so it suits medium-pressure return lines. A peak flow rate of 50 l/min supports actuators that draw moderate volume. The coil operates on 24 V DC and draws 1.25 A. Wiring is made through a DIN EN 175301-803 connector with three poles and a protective earth conductor. The subplate interface follows ISO 4401-03-02-0-05, and the body can be installed in any orientation without performance loss.
Ingress protection rated IP65 shields internal components from dust and water jets. The hydraulic fluid must meet ISO 4406 (c) 20/18/15 cleanliness to prevent spool abrasion. A concealed manual override allows local actuation during service and remains operable with up to 50 bar in the tank line. NBR seals retain pressure while tolerating standard mineral oils. Mounting is completed with M5 screws tightened to 7 Nm, ensuring a rigid joint between valve and subplate. Mean time to dangerous failure is 150 years, providing quantified reliability for safety calculations. These features keep the valve secure in wet environments, easy to service, and dependable over long machine life.
