A forging manipulator works with short, hard load changes and needs a steady pilot stage for that. The 4WRKE16E150L draws pilot oil from outside and meters 150 l/min nominal flow at up to 350 bar. Its weight is 11.8 kg.

Total price
A forging manipulator reverses load and direction at short intervals, which puts demands on the pilot stage of a valve. On the 4WRKE16E150L-3X/6EG24K31/A1D3M pilot supply and pilot drain are therefore external, keeping pilot pressure independent of the main circuit, at 150 l/min nominal flow and 350 bar operating pressure.
Benefits
- External pilot path on both sides, pilot pressure stays steady through load changes
- 150 l/min nominal flow, headroom up to 460 l/min maximum flow
- 350 bar operating pressure in size 16 on the ISO 4401-07-07-0-05 pattern
- Internal position feedback with on-board electronics, ±10 V command value at 24 VDC
- Spool symbol E, NBR seals, 11.8 kg, HL hydraulic fluid
