Warm oil calls for FKM, a fluctuating main pressure calls for a pilot source of its own. This version of the 4WRKE series brings both together and controls 350 l/min nominal flow at 350 bar linearly over the stroke.
Benefits
- FKM seals for permanently warm oil of hydraulic fluid class HL.
- External pilot oil supply and external return keep the pilot stage independent of the main circuit.
- 350 l/min nominal flow at 350 bar, flow up to 870 l/min.
- 4 to 20 mA command value on the on-board electronics, internal spool position feedback.
- Spool symbol R3, 3 switching positions, 17.84 kg installed weight.
