An axis running at 50 l/min needs no more than size 10, provided it works under position control. The 4WRTE10V50L-4X uses spool symbol V, processes the ±10 V command value in its on-board electronics and takes pilot oil internally, so only four ports need piping.

Total price
An axis with an oil demand of around 50 l/min does not need a big valve, it needs an accurate one. This pilot-operated size 10 proportional valve works with spool symbol V, internal spool position feedback and on-board electronics that evaluate the ±10 V command value at the unit itself.
Benefits
- 50 l/min nominal flow, up to 170 l/min across the valve
- Spool symbol V with a linear characteristic curve and internal spool position feedback
- On-board electronics, ±10 V command value, 24 VDC supply
- Internal pilot oil supply and internal pilot oil return
- ISO 4401-05-05-0-05 port pattern, FKM seals, weight 9.5 kg
