The 4WRZ32W6-520-7X/6EG24N9K4/V valve belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and is intended to control flow and direction in hydraulic automation systems. It is built in size 32 to carry the required passage area for large circuits, and it delivers a nominal flow of 520 l/min at a 10 bar differential so actuators receive oil quickly. The solenoid is energized with 24 V DC and can draw as much as 1.5 A, while a coil resistance of 4.8 Ω at 20 °C determines the electrical load. A 100 percent duty cycle allows uninterrupted service, and the winding tolerates temperatures up to 150 °C without loss of performance. Electrical hookup uses a DIN EN 175301-803 connector, giving installers a standard interface for field wiring.
The valve includes a concealed manual override that lets technicians shift the spool during commissioning without power. An IP65 rating, once a cable socket is attached, keeps dust and water jets away from internal parts. FKM seals withstand aggressive hydraulic fluids and elevated temperatures, and a maximum operating pressure of 350 bar permits use in high-pressure machinery. The pilot stage is built in size 6, and both pilot oil supply and pilot oil drain are external so control pressure remains independent of main line changes. A porting pattern of ISO 4401-10-08-0-94 matches common sub-plates for this body size, completing a configuration that supports precise proportional control in demanding installations.
