The 4WRZE16W6-100-7X/6EG24N9ETK31/F1V proportional directional valve belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and is used to control hydraulic flow and direction in automation systems. It receives a 4 to 20 mA command signal so an electronic controller can adjust the spool position proportionally. A 24 VDC supply voltage energizes the solenoids, and peak demand is limited to 1.8 A. Spool type W6 defines the metering edges, while size 16 establishes the mounting pattern and flow path dimensions, allowing a nominal flow of 100 l/min at a 10 bar pressure drop. Internal pilot oil supply eliminates the need for an external pilot line, and internal pilot oil drain returns pilot fluid to tank without additional fittings. An electrical plug in accordance with DIN EN 175201-804 provides the interface for power and signal wiring.
The valve withstands a maximum operating pressure of 350 bar in the service ports and limits port T backpressure to 30 bar when drained internally. Hysteresis is kept at or below 6%, supporting repeatable spool positioning. FKM seals permit use with a range of hydraulic fluids, and the coil remains functional up to 150 °C. A concealed manual override allows mechanical shifting during commissioning or power loss. The assembly weighs 13.6 kg, giving it the mass needed for stable manifold mounting. These features enable proportional flow and directional control under demanding hydraulic conditions.
