When the axis runs on a fieldbus instead of an analogue input, the command wiring disappears. The 4WRLF series carries the fieldbus electronics inside the valve and needs only a 7-pole connector for supply voltage and enable acknowledgment. Size 25, 400 l/min nominal flow, 280 bar, spool symbol E1.

Instead of a command line and a feedback cable, this 4WRLF25E1-400LJ-4X/MPT00/24ND90 only needs its bus link: the fieldbus electronics are built into the valve and the 7-pole connector carries supply voltage and enable acknowledgment. The main circuit provides 400 l/min nominal flow at 280 bar.

Key benefits

  • Integrated fieldbus electronics, wired through a 7-pole connector (6 + PE) instead of a multi-core analogue cable.
  • 400 l/min nominal flow in size 25, up to 1250 l/min maximum flow.
  • 280 bar operating pressure with internal pilot oil supply and internal pilot oil return.
  • Spool symbol E1, 3 switching positions, 4 ports, internal spool position feedback.
  • 24 VDC supply voltage, command value and diagnostics travel over the bus.
  • 18.58 kg on a subplate to ISO 4401-08-08-0-05, NBR seals for HL hydraulic fluid.

Applications

The version fits machines whose axes are already coordinated over a fieldbus, such as press lines and test installations. Wiring effort drops because each valve needs only one supply plug plus the bus cable. Internal pilot supply also removes the control oil plumbing.
