A separate pilot line becomes unnecessary when the valve taps pilot pressure internally. The 4WRLE27E1-600LJ-4X works that way, controls 600 l/min nominal flow in size 27 and accepts 4 to 20 mA as its command value. Symbol E1, 20.82 kg.

Internal pilot oil supply saves one line plus one possible fault point in the manifold. The 4WRLE27E1-600LJ-4X/MPY/24F1 draws from the main gallery, routes pilot oil return to the outside and converts 600 l/min of nominal flow.
Benefits
- Internal pilot oil supply, no separate feed line for pilot pressure.
- External pilot oil return, keeping the pilot stage clear of back pressure in the tank line.
- 600 l/min nominal flow, up to 1850 l/min maximum flow.
- Command value 4 to 20 mA at 24 V DC, on-board electronics.
- Symbol E1, 270 bar operating pressure, connection diagram ISO 4401-08-07-0-05.
- 20.82 kg, NBR seals, CE conformity.

Applications
It pays off in manifolds where every extra bore means work and system pressure is present anyway. At 600 l/min nominal flow the valve fits main axes driving large cylinder areas.
