Proportional Directional Valve 4WRLF25W6-350LJ-4X/MPY00/24ND90 - Bosch Rexroth R901569785

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.

Application

The valve suits hydraulic axes in plastics machinery, rolling mills and test benches that are commanded from a PLC over the bus. On the ISO 4401-08-08-0-05 interface it fits any matching size 25 subplate. At 18.58 kg a fixed installation position with lifting aid makes sense.
