A manifold with fewer drillings saves assembly time. The 4WRZ25E1-220-7X/6EG24N9ETK4/M feeds pilot oil internally and drains it internally, so X and Y lines are dropped. 220 l/min nominal flow, spool symbol E1, concealed auxiliary actuation.

Total price
The fewer external pilot lines a manifold needs, the fewer fittings can leak. The 4WRZ25E1-220-7X/6EG24N9ETK4/M is pilot operated entirely internally and controls 220 l/min nominal flow on the ISO 4401-08-08-0-05 pattern.
Benefits
- Internal pilot supply and internal return, neither an X nor a Y line has to be routed.
- 220 l/min nominal flow, up to 870 l/min flow in size 25 with spool symbol E1.
- Concealed auxiliary actuation for function checks without a connected amplifier.
- 20.18 kg weight at 350 bar maximum operating pressure, three switching positions and four ports.
- NBR seals, HL hydraulic fluid, supplied with 24 VDC through a 7-pole (6 + PE) plug.

Applications
The valve suits compact manifolds on machine tools, lift tables and test equipment where block space is tight. Fully internal pilot operation assumes that the main circuit delivers pilot pressure within the permitted range and that the tank line carries only low back pressure.
Manufacturer
Bosch Rexroth, material number R901212661. Limits for pilot pressure and back pressure along with the characteristic curves are given in data sheet RE 29115, range overview in RE 07600-B.
