4WRZ10E1-25-7X/6EG24N9K4/V

The 4WRZ10E1-25-7X/6EG24N9K4/V belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and directs hydraulic fluid in automated motion circuits. It delivers a nominal flow of 25 l/min at a differential pressure of 10 bar, letting actuators move at predictable speeds. The main stage tolerates operating pressures up to 315 bar so it can be installed in high-pressure power units. A porting pattern conforming to ISO 4401-05-05-0-94 matches standard subplates for straightforward mounting. The valve is intended for systems that use mineral oil classified as HL or HLP which maintains lubrication and seal compatibility. Acceptable fluid temperatures lie between −20 and +80 °C permitting cold start and elevated temperature duty without damage. It works with viscosities from 20 to 380 mm²/s, providing stable spool positioning across typical oil grades. An IP65 enclosure rating protects the solenoid and electronics against dust and water spray during outdoor service. A concealed manual override designated N9 lets technicians shift the spool during commissioning or power loss without removing covers.

Cleanliness of the main stage must meet ISO 4406 class 20/18/15, reducing the risk of spool seizure from particulate contamination. Solenoid power is supplied at 24 V DC, aligning with common machine control panels. The coil draws a maximum of 1.5 A, allowing modest wiring sizes and limiting heat generation. Electrical connection is made through a DIN EN 175301-803 plug which enables quick disconnection for maintenance. The valve can be energized continuously because its duty cycle is 100%, supporting uninterrupted closed-loop control. Output hysteresis does not exceed 6%, ensuring repeatable flow characteristics around setpoints. Return flow at port T may be subjected to pressures up to 315 bar so external drain lines can be routed into pressurized tanks. For subplate mounting the assembly weighs 7.8 kg, which facilitates single-person installation with standard tools.
