When pilot oil should come from a dedicated, filtered circuit, the version with external supply and external return is the right one. The 4WRKE25R3-350L then meters 350 l/min nominal flow from a 4...20 mA command and keeps the closed mid position of symbol R3.

Description

A separate pilot circuit with its own filtration protects the sensitive pilot stage. The 4WRKE25R3-350L-3X/6EG24K31/F1D3M is built for that, taking pilot oil externally and returning it externally while the main spool releases 350 l/min at up to 350 bar.

Benefits

External pilot oil supply and external return allow a dedicated pilot circuit
Spool symbol R3 with all ports blocked in mid position
350 l/min nominal flow in size 25
4...20 mA current command on the on-board electronics
Internal spool position feedback for reproducible positioning

Applications

Found in steel plants, roll adjustment drives and systems with a high contamination risk in the main circuit. The separate pilot circuit can be filtered and monitored independently. Interface ISO 4401-08-08-0-05, weight 17.9 kg.
