Proportional Directional Valve 4WRZE10W6-50-7X/6EG24N9TK31/A1M - Bosch Rexroth R901454471

The 4WRZE10W6-50-7X/6EG24N9TK31/A1M is the voltage variant of this series: the command value arrives as ±10 V, the nominal rating is 50 l/min and operating pressure reaches 315 bar. Pilot oil comes from outside while the return runs internally.

Advantages

• Analog ±10 V command input matching standard machine controller outputs
• Nominal flow 50 l/min against a maximum flow of 170 l/min
• Operating pressure to 315 bar, W6 spool, 3 switching positions
• External pilot oil supply and internal pilot oil return, no pressure reducing valve
• Concealed auxiliary actuation so the axis can be moved with the power off
• UKCA conformity for electromagnetic compatibility SI2016/1091

Applications

The variant fits plants whose controller emits a voltage, such as forming presses, lifting gear or hydraulic feed axes drawing around 50 l/min. During service or first start-up the spool can be shifted by the concealed auxiliary actuation. NBR seals match HL oil.

Manufacturer

Bosch Rexroth assigns material number R901454471 to this version. Data sheet RE 29115 for pilot-operated proportional directional valves carries the characteristic curves and port dimensions, and RE 07600-B adds the general hydraulic valve data.
