The 4WRZE25E325-7X/6EG24N9ETK31/A1V valve belongs to the WRZ Proportional Directional Valves series manufactured by Bosch Rexroth. It meters flow to hydraulic actuators in automated machinery, using a spool positioned by onboard electronics. The valve is built in size 25 and follows the ISO 4401-08-07-0-94 porting pattern so it mounts directly to matching subplates. At a 10 bar differential, the nominal flow capability is 325 l/min, while the design withstands operating pressures up to 350 bar for high-power circuits. Both pilot oil supply and pilot oil drain are internal, removing the need for extra external lines. An FKM seal set resists mineral oils and many synthetic fluids, and a DIN EN 175201-804 plug provides the electrical connection.
The electronics accept a 24 V DC supply, and the control stage is intended for direct-current operation. A ±10 V command value input shifts the spool proportionally, and coil current is limited to 1.8 A to protect the winding. Maximum hysteresis is 6 %, supporting repeatable positioning during cycling. The housing reaches an IP65 protection rating to block dust and water jets, and reliable function is maintained in ambient temperatures up to 50 °C without derating. Installed weight is 18.4 kg, which should be considered when sizing the mounting surface and support hardware.
