Description

If system pressure drops sharply during the cycle, the pilot stage needs its own source. This variant of the 4WRKE27E500L-3X uses external pilot oil supply and external return while controlling 500 l/min with internal position feedback.

Benefits

External pilot oil supply keeps the pilot stage responsive regardless of main pressure
External pilot oil return relieves the main circuit return line
500 l/min nominal flow, up to 1000 l/min peak flow
Internal spool position feedback with a linear characteristic curve
FKM seals, hydraulic fluid HL, 270 bar operating pressure
Size 27 with subplate mounting to ISO 4401-08-08-0-05

Applications

Useful in circuits with accumulator operation or strongly varying load where main pressure collapses briefly. The pilot stage also stays supplied during long holding phases. The 19.22 kg weight is typical for size 27.
