The 4WRZE25W8-220-7X/6EG24N9K31/A1D3V proportional directional valve belongs to the WRZ Proportional Directional Valves series and is produced by Bosch Rexroth. It directs flow in hydraulic systems where precise motion is required. The valve is supplied in size 25, which determines the mounting footprint and flow path dimensions, while ports A, B, and T share a 25 mm diameter to maintain full-bore passage. A nominal flow of 220 l/min at a 10 bar differential allows the unit to serve large actuators without significant pressure loss, and it tolerates system pressures up to 350 bar for high-pressure circuits. A 24 V DC supply energizes the solenoids, and proportional control is achieved with a ±10 V command signal that the electronics interpret linearly. The DIN EN 175201-804 electrical connector provides a standardized interface for power and feedback wiring. The ISO 4401-08-07-0-94 port pattern aligns the valve body with common subplates, and the assembly weighs 18.4 kg, so mounting hardware must support that load.
For pilot functions, the design employs external pilot oil supply and external pilot oil drain, separating control flow from the main line to improve stability. A 3DREP 6 pilot valve generates the proportional metering pressure, while an integrated ZDR 6 DP0-4X/40YM-W80 pressure reducing valve limits pilot pressure to the required level. A concealed manual override is included for local shifting during commissioning or in case of electrical failure. The T port can withstand 250 bar when an external drain is used, permitting back-pressure in return lines without damaging the housing. The coil winding endures temperatures up to 150 °C, enabling continuous duty in hot ambient conditions or when mounted near heat sources. Together, these features keep the valve responsive and protect the pilot stage under variable load and temperature conditions.
