Permanently warm oil attacks NBR, so this size 25 4WRKE carries FKM seals. The valve controls 350 l/min nominal flow at 350 bar with a linear characteristic curve and a 4 to 20 mA command value through spool symbol R3.

In plants whose oil runs warm around the clock the sealing material decides service life. This pilot-operated proportional directional valve of the 4WRKE series therefore uses FKM seals and controls 350 l/min nominal flow at 350 bar.
Benefits
- FKM seals withstand higher oil temperatures than the NBR version of the same size.
- Linear characteristic curve over the full stroke, good for a steady speed setpoint.
- 350 l/min nominal flow at 350 bar, flow up to 870 l/min.
- 4 to 20 mA current command value, insensitive to interference on long cable runs.
- Internal pilot oil supply and internal return, spool symbol R3, 17.92 kg.
