The 4WRZ16E1-150-7X/6EG24N9K4/D3V valve belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and directs hydraulic flow in automated circuits. It is built in size 16 and follows the ISO 4401-07-06-0-94 mounting pattern, so it fits standard subplates of that size. A 24 V DC supply energizes the solenoid, which presents a coil resistance of 4.8 Ω at 20 °C; this value sets the electrical load seen by the power supply. The duty cycle is 100 percent, allowing the coil to stay energized without scheduled rest periods. Current draw is limited to 1.5 A, defining the driver output that must be provided. Hysteresis stays at or below 6 percent, helping the valve reproduce command signals with predictable spool positions.
The main ports tolerate operating pressures up to 350 bar, while port Y is restricted to 30 bar and the external drain line supports 250 bar, so circuit designers can assign return flow correctly. A nominal flow of 150 l/min at a 10 bar differential characterizes the throughput available when the valve is fully shifted. The coil can reach 150 °C without damage, which safeguards performance in hot manifolds. Ingress protection is rated IP65 when the DIN EN 175301-803 electrical connector is fitted, enabling installation in dusty or damp machine areas. An FKM seal package resists common hydraulic oils and elevated temperatures, and the complete assembly weighs 13.4 kg, influencing manifold support and handling methods.
