If the controller only has a ±10 V voltage output free, this version fits straight away. It controls 220 l/min nominal flow at 350 bar, carries spool symbol E and draws pilot oil internally with external return. Supply is 24 VDC.

Total price
Not every controller has a current output to spare, while a ±10 V voltage output is nearly always available. This version of the 4WRZE25 takes exactly that signal and turns it into 220 l/min nominal flow at 350 bar, with spool symbol E and internal pilot supply.
Benefits
- ±10 V voltage command without an extra converter card in the control cabinet.
- 220 l/min nominal flow for medium axes, up to 870 l/min at peak.
- 350 bar operating pressure on a valve that fits the ISO 4401-08-08-0-05 pattern.
- Internal pilot supply and external pilot return keep the pilot stage clear of tank back pressure.
- On-board electronics with a 7-pole connector (6 + PE), 24 VDC supply.
