Running a hydraulic axis under closed-loop position control normally means a valve plus a separate controller card. This size 25 4WRLD carries the digital axis controller on board and meters 400 l/min nominal flow at 350 bar. The command value arrives as an analog ±10 V signal through the 12-pole connector.

A hydraulic axis should hold its own position without a controller card taking up cabinet space and wiring. The 4WRLD25W8-350LJ-4X/MXY/24ND6T covers both jobs in one device, metering 400 l/min nominal flow at 350 bar operating pressure with the digital axis controller mounted on the valve body.

Benefits

  • Integrated axis controller - closed-loop control runs on the valve electronics, powered from 24 V DC, so no external amplifier card is required.
  • 400 l/min nominal flow in size 25, with up to 1250 l/min possible by design.
  • 350 bar operating pressure across all four ports, rated for HL hydraulic fluid with NBR seals.
  • Symbol W8 with three switching positions for cylinders and motors that travel under control in both directions.
  • Internal spool position feedback keeps the spool on the command value even against high flow forces.
  • External pilot oil supply and external pilot oil return keep the pilot circuit separate from the main circuit.

Application

The usual home for this valve is a servo axis in presses, test rigs and forming equipment where position or velocity is commanded by a higher-level controller. The ISO 4401-08-08-0-05 interface allows a direct swap against other size 25 valves on existing subplates. At 18.58 kg it belongs in stationary power units.
