Total price
A separate pilot line becomes unnecessary once the main circuit provides enough pressure. That is what this version of the 4WRKE27E500L-3X is built for, with internal pilot oil supply, external return and a plus/minus 10 V command value for 500 l/min nominal flow.
Benefits
- Internal pilot oil supply cuts the piping effort at the subplate
- 500 l/min nominal flow, 1000 l/min peak at 270 bar operating pressure
- The plus/minus 10 V command value matches the common analog outputs of standard controllers
- Internal spool position feedback keeps the characteristic curve reproducible
- FKM seals widen the operating range compared with NBR
- Spool symbol E with four ports and three switching positions
