Large cylinders call for flow, long cable runs call for a current signal. The 4WRKE25E350L-3X/6EG24K31/F1D3M brings both together: 350 l/min nominal flow in size 25 and a 4...20 mA command, with pilot oil arriving from outside and returning outside.
Key benefits
- 350 l/min nominal flow in size 25, maximum flow through the valve 870 l/min.
- A 4...20 mA command stays immune to interference over long cable runs, supplied with 24 VDC.
- Spool symbol E with 3 switching positions and 4 ports to ISO 4401-08-08-0-05.
- External pilot oil supply and external return for power units with a dedicated pilot pump.
- Internal spool position feedback, linear characteristic curve, 17.9 kg weight.
- NBR seals for HL hydraulic fluid, 7-pole connector (6 + PE) to EN 175201-804.

Applications
Intended for main axes on presses, forging lines and lift tables whose cylinders swallow a lot of oil in a short time. An operating pressure of 350 bar allows smaller piston areas for the same force. Since the pilot stage has its own supply, it stays functional when the main circuit loses pressure.
