Proportional Directional Valve 4WRZE10E85-7X/6EG24N9EK31/F1M - Bosch Rexroth R901213532
This 85 l/min version takes pilot oil internally and drains it externally, which helps on manifolds with back pressure in the return. It carries an E spool, works to 315 bar and follows a 4 to 20 mA command value.

Description
The 4WRZE10E85-7X/6EG24N9EK31/F1M combines the large 85 l/min rating with internal pilot oil supply and external pilot oil return. Maximum operating pressure is 315 bar and the valve weighs 8.76 kg.
Advantages
- Nominal flow 85 l/min, maximum flow 170 l/min
- Internal pilot oil supply and an external, back-pressure free pilot oil return
- E spool, 3 switching positions, 4 ports, operating pressure to 315 bar
- Concealed auxiliary actuation, built without a pressure reducing valve
- On-board electronics, 4 to 20 mA command value, 24 V DC through an EN 175201-804 connector
- UKCA conformity for electromagnetic compatibility SI2016/1091
Applications
This combination is wanted in systems where several consumers share one return line and tank pressure rises. The 85 l/min rating serves cylinders in presses and lifting gear. NBR seals are provided for HL oil.
Manufacturer
Bosch Rexroth lists the valve as R901213532. Characteristic curves, pilot oil demand and installation dimensions are in data sheet RE 29115, with RE 07600-B covering the hydraulic valves in general.
