A nominal flow of 25 l/min makes this version useful for slow, closely guided motions. A pressure reducing valve in the pilot stage holds pilot pressure constant, and switching follows symbol E.

Total price
The smaller the nominal flow, the more finely an axis can be guided. At 25 l/min this size 10 valve is laid out for slow infeed and positioning motions. The built in pressure reducing section keeps the pilot stage at constant pressure, and 170 l/min are possible at maximum.
Benefits
- Nominal flow 25 l/min for slow and closely guided motions
- Pressure reducing valve in the pilot stage, giving consistent behaviour across the pressure range
- Symbol E in 3 switching positions across 4 ports
- Internal pilot oil supply and internal pilot oil return
- Maximum flow 170 l/min at an operating pressure of up to 315 bar
- NBR seals, subplate mounting to ISO 4401-05-05-0-05, mass 8.22 kg

Applications
Typical duty is on infeed axes, test cylinders and handling drives that should start smoothly and hold position accurately. The small rating spreads the command range across a narrow flow.
