Driving a large cylinder axis over a fieldbus only works if the valve speaks the bus itself. This size 25 4WRLF carries the fieldbus electronics on board and handles 400 l/min nominal flow at 280 bar operating pressure. Internal pilot oil supply saves a dedicated pilot line.

In networked machines the command value, the enable signal and the acknowledgment travel over the bus instead of individual analog wires. The 4WRLF25W6-350LJ-4X/MPY00/24ND90 is built for that, metering 400 l/min nominal flow at 280 bar operating pressure and reporting its status through the integrated fieldbus electronics.
Benefits
- Fieldbus electronics in the valve - voltage supply, enable and acknowledgment run through the 7-pole connector to EN 175201-804.
- 400 l/min nominal flow in size 25, with a design ceiling of 1250 l/min.
- 280 bar operating pressure as the maximum working pressure across the four ports, HL hydraulic fluid.
- Internal pilot oil supply with external pilot oil return, so only one extra line to tank is needed.
- Symbol W6 with three switching positions and internal spool position feedback for repeatable positioning.
