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
