A test rig with its own pilot pump and long signal runs needs both: external pilot supply and a current command. This 4WRLE16E1-250LJ delivers 250 l/min nominal, is driven by 4...20 mA and controls the main spool through internal position feedback. Limit 800 l/min at 350 bar.

Total price
The highest flow rating of size 16 can only be used if the pilot stage receives enough pressure. This version therefore takes pilot oil externally at X and drains externally at Y, independent of what happens in the working circuit. The command arrives as a 4...20 mA current signal and internal position feedback holds the main spool at 250 l/min nominal.
Benefits
- 250 l/min nominal flow with an 800 l/min limit at 350 bar.
- External pilot supply and external drain keep pilot pressure independent of working pressure.
- Command value 4...20 mA, a broken wire shows as loss of the live zero current.
- Internal main spool position feedback with linear characteristic, symbol E1.
- On-board electronics fed from 24 VDC, no controller card in the cabinet.
- CE conformity, valve weight 11.62 kg, port pattern ISO 4401-07-07-0-05.

Applications
The valve runs materials testing machines, fatigue rigs and large cylinder axes with a separate pilot power unit. Because the pilot circuit is fed on its own, the main spool can be moved even when the working circuit is unpressurised. The subplate must carry the X and Y channels.
