The 4WRZ16E1-150-7X/6EG24N9K4/V proportional directional valve belongs to the WRZ Proportional Directional Valves series and is manufactured by Bosch Rexroth for closed-loop hydraulic automation. It is energized by a 24 VDC supply, and its coil resistance of 4.8 Ω establishes the electrical load seen by a drive card. A maximum coil current of 1.5 A limits the output stage of the controller, while a permissible coil temperature of 150 °C defines the safe thermal range during continuous duty. Connection is made through a DIN EN 175301-803 plug, and a mated plug provides IP65 protection so the solenoid remains sealed against dust and low-pressure water. Electrical hystereses are contained to 6 %, helping the valve repeat commanded positions with minimal deviation and ensuring stable flow control under varying loads.
The unit mounts to a subplate that follows the ISO 4401-07-06-0-94 pattern, which standardizes port locations for interchangeability. It supports a nominal flow of 150 l/min at a 10 bar differential, enabling medium-capacity actuator circuits, and withstands a main operating pressure of 350 bar for high-pressure systems. Return flow at port T can reach 250 bar without damage, whereas port Y is limited to 30 bar to protect the pilot stage. Pilot oil is supplied and drained externally, and a pilot flow of 5.5 l/min is needed to move the spool from 0 to 100 % stroke, allowing remote control independent of main line pressure. The assembled valve weighs 13.4 kg, a factor considered when selecting manifold supports or handling equipment during installation.
