Total price
Motion controllers usually deliver their command as a voltage, and the axis should accept it without a detour. This 4WRZE25 with spool symbol W6 processes ±10 V directly and sets 220 l/min nominal flow at 350 bar from it.
Benefits
- ±10 V command straight from the motion controller, with no converter in between.
- 220 l/min nominal flow, maximum flow 870 l/min.
- Internal pilot supply with external return, one line less than the fully external routing.
- Three switching positions and four ports on the ISO 4401-08-08-0-05 interface.
- 20.22 kg with on-board electronics and 24 VDC supply.
