The 4WRZE16E1-150-7X/6EG24N9EK31/A1V valve belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and modulates flow and direction in hydraulic automation circuits. It operates on a 24 V DC supply voltage and accepts a ±10 V command signal for spool positioning. A DIN EN 175201-804 plug serves as the electrical connection, while a concealed manual override permits local actuation when needed. Nominal size 16 provides a standardized interface and supports a rated flow of 150 l/min at a 10 bar pressure differential. Hysteresis does not exceed 6%, allowing repeatable valve behavior within tight control loops. The mounting pattern follows ISO 4401-07-06-0-94 for direct stacking on subplates.
In service, the valve withstands 350 bar on ports P, A, and B and tolerates 250 bar on port T when an external drain is used. Internal pilot supply with an external drain simplifies plumbing yet keeps back pressure low. Continuous operation draws a maximum of 1.8 A, and a 3 A power pulse current is available for rapid spool shifts. Total mass is 13.6 kg, so installation requires suitable support. FKM (Viton) seals resist common hydraulic fluids and high temperatures.
