The 4WRZE16W8-100-7X/6EG24N9EK31/A1D3M valve is part of the WRZ Proportional Directional Valves series from Bosch Rexroth and is intended for closed-loop hydraulic automation. It delivers a nominal flow of 100 l/min at a 10 bar differential to regulate actuator speed while tolerating system pressures up to 350 bar. Installation is simplified by an ISO 4401-07-06-0-94 mounting interface that aligns with standard subplates. The integrated electronics accept a ±10 V command signal and run on a 24 V DC supply, drawing up to 1.8 A during steady operation. Continuous service is supported by a 100 % duty cycle rating, and internal pilot oil supply eliminates external pilot plumbing. A concealed manual override permits local spool motion, and an onboard ZDR 6 DP0-4X/40YM-W80 pressure reducing valve keeps pilot pressure stable under load changes.
A solenoid limit of 2.5 A defines the maximum steady magnetizing current, while a 3 A power pulse accelerates the spool at actuation onset. The DIN EN 175201-804 connector provides a common industrial interface for electrical wiring, and the coil is specified for temperatures up to 150 °C to withstand hot oil environments. An IP65 housing protects the assembly from dust ingress and water jets, making it suitable for exposed machinery. The unit weighs 13.6 kg, so it can be installed by one technician using standard lifting methods. These parameters combine to offer precise proportional flow control and dependable performance in presses, injection molding machines, and other automated hydraulic equipment.
