The 4WRZE16E2-150-7X/6EG24N9ETK31/F1D3V valve belongs to the WRZ Proportional Directional Valves series and is produced by Bosch Rexroth for closed-loop hydraulic motion control. It delivers a nominal flow of 150 l/min at a 10 bar differential pressure to adjust cylinder or motor speed, and it tolerates main port pressures up to 350 bar for high-pressure systems. Command signals of 4–20 mA permit direct interface with common process controllers, while a 24 V DC supply and a maximum current draw of 1.8 A define the electrical load on the power supply. The mounting interface follows ISO 4401-07-06-0-94 so it can be bolted to standard size-16 subplates, and IP65 ingress protection shields the coils from dust and water spray. Hysteresis kept to 6 percent or less supports accurate directional metering, and FKM seals resist heat and aggressive oils.
The valve uses an internal pilot oil supply, and an internal pilot oil drain routes pilot flow back without external tubing, simplifying manifold layout. A return port pressure limit of 30 bar on the internal drain prevents spool disturbance under back-pressure conditions. Pilot control is handled by a size-6 solenoid stage, and a pressure reducing valve type ZDR 6 DP0-4X/40YM-W80 maintains a stable pilot pressure for consistent main-stage response. Electrical connection is made through a DIN EN 175201-804 component plug to standardize wiring, and a concealed manual override lets technicians shift the spool during commissioning without exposing the mechanism. These characteristics support reliable proportional flow and pressure regulation when the valve is installed in mobile or industrial hydraulic manifolds.
