A large axis without its own pilot circuit can still be built with internal pilot supply. The 4WRDE27V500L-6X/MPT/24A1 feeds plus drains its pilot stage internally, controls 500 l/min nominal flow and works to 270 bar operating pressure.

Retrofitting a large axis often means no separate pilot circuit is available. The 4WRDE27V500L-6X/MPT/24A1 solves that internally: pilot supply plus drain run inside the valve, leaving 500 l/min nominal flow at 270 bar operating pressure with up to 1000 l/min at peak.
Key benefits
- Internal pilot oil supply plus internal return save two pipe runs during a retrofit.
- Nominal flow of 500 l/min, peak flow of 1000 l/min, operating pressure of 270 bar.
- On-board electronics with internal piston position feedback on a plus or minus 10 V command.
- Spool symbol V, 3 switching positions, 4 ports, interface ISO 4401-08-08-0-05.
- Connector, 7-pole to EN 175201-804, mass of 19.5 kg, NBR seals.

Applications
Fields of use are press cylinders, lifting gear in steel plants plus large test axes. With internal pilot supply the system pressure has to stay above the minimum pilot pressure, otherwise the axis loses dynamics. HL is the intended hydraulic fluid.
Manufacturer
Manufacturer Bosch Rexroth, type 4WRDE27V500L-6X/MPT/24A1, material number R901555480. Pilot routing is fixed mechanically, so converting an MPT build to external supply in the field is out of scope.
