On a vibration test rig what counts is that the spool follows the command value without delay. The ETK31 version of the 4WRKE16W6-150L works without an external pilot line and meters 150 l/min nominal flow. Operating pressure reaches 350 bar at a weight of 12.96 kg.

Total price
On a vibration test rig the spool has to follow a changing command value without delay. The 4WRKE16W6-150L-3X/6EG24ETK31/A1D3M keeps the control loop short because position feedback works internally and the pilot paths also stay inside the valve.
Benefits
- Internal position feedback with on-board electronics, a short loop without an external amplifier
- Pilot oil in and out internally, no extra piping on the rig
- 150 l/min nominal flow, up to 460 l/min maximum flow
- 350 bar operating pressure in size 16, weight 12.96 kg
- ±10 V command value, 24 VDC, NBR seals, spool symbol W6
