Description
The 4WRZ10W8-25-7X/6EG24N9ETK4/V uses fully internal piloting and therefore needs no additional pilot lines in the block. Nominal flow is 25 l/min.
Advantages
- Internal pilot oil supply and internal pilot oil return, leaving the block free of X and Y drillings.
- Nominal flow of 25 l/min for finely guided movements.
- Symbol W8 in three switching positions, total flow up to 170 l/min.
- Operating pressure up to 315 bar, connection diagram ISO 4401-05-05-0-05.
- Concealed manual override, FKM seals, weight 7.8 kg.
Application
Compact manifold blocks benefit from not having to drill separate pilot lines. The valve controls slow axes in machine tools, clamping systems and test set-ups. System pressure has to stay high enough for piloting at all times.
Manufacturer
Bosch Rexroth lists the valve under material number R900956998. Curves and port dimensions are given in the data sheet in the download section.
