The 4WRZE16W8-150-7X/6EG24N9EK31/A1V valve belongs to the WRZ Proportional Directional Valves series and is produced by Bosch Rexroth to modulate flow and direction in hydraulic automation circuits. A main operating pressure limit of 350 bar supports high-pressure systems, while a nominal size of 16 defines the port configuration for medium frame manifolds. The metering section handles a nominal flow of 150 l/min at a 10 bar differential to deliver rapid actuator response. Electronic command is accepted as a ±10 V signal, and the onboard electronics are powered from a 24 V DC supply. Internal pilot oil supply simplifies plumbing, whereas an external pilot drain prevents pressure buildup in the control cover. Valve hysteresis remains at or below 6 percent to maintain repeatable spool positioning.
The valve mounts on an ISO 4401-07-06-0-94 interface so it can drop onto standard subplates, and the assembly weight of 13.6 kg allows single-person handling during maintenance. Its pilot stage corresponds to size 6, matching common NG6 logic covers. Port Y may see up to 30 bar, protecting the drain line from excessive back pressure, while the external return port T tolerates 250 bar to suit boosted tank circuits. Electrical connection is made through a plug conforming to DIN EN 175201-804, facilitating quick coil exchange. A concealed manual override lets technicians shift the spool without energizing the solenoid. FKM seals resist high temperature hydraulic fluids and many synthetic oils, completing the fluid compatibility profile.
