Proportional Directional Valve 4WRLF27E600LJ-4X/MXY00/24ED90 - Bosch Rexroth R901565051

The more controlled axes a plant has, the more costly analog wiring becomes. The 4WRLF27E600LJ-4X/MXY00/24ED90 valve in size 27 therefore carries integrated fieldbus electronics, works at 600 l/min nominal flow, passes up to 1850 l/min and is rated for 270 bar operating pressure.

Key benefits

• Integrated fieldbus electronics, set point and diagnostics run over one link instead of separate analog lines
• 600 l/min nominal flow, 1850 l/min maximum, controlled with internal spool position feedback
• 7-pole connection (6 + PE) to EN 175201-804 with voltage supply and enable acknowledgment, so the release is reported back
• Symbol E with 4 ports and 3 switching positions, mounting pattern ISO 4401-08-08-0-05
• External pilot oil supply and external pilot oil return, 270 bar maximum operating pressure
• NBR seals for HL hydraulic fluid, UKCA record for electromagnetic compatibility to SI2016/1091, weight 20.18 kg

Application

The valve suits plants with several large control axes, for example press lines and test fields where set points and status data are managed centrally. The enable acknowledgment can be tied into the safety logic of the plant. Pilot oil is supplied and returned externally.
