Proportional Directional Valve 4WRLD27E600LJ-4X/MXT/24ND6T - Bosch Rexroth R901471403

Between fully external and fully internal pilot routing sits an intermediate step that saves one line. This size 27 variant draws pilot oil from an external supply but returns it internally, and controls 600 l/min nominal flow at 270 bar operating pressure with an integrated digital axis controller.

Benefits

• External supply, internal return - pilot pressure stays independent while the separate Y line to tank is no longer needed.
• 600 l/min nominal flow and up to 1850 l/min maximum flow at 270 bar.
• E spool symbol with internal spool position feedback for a repeatable characteristic.
• Digital axis controller on board, analogue ±10 V command value on the 12-pole connector (11 + PE), 20.78 kg on the ISO 4401-08-08-0-05 pattern.

Application

This pilot arrangement suits plants that have their own pilot pressure source but whose tank line at the valve is unpressurised anyway. Piping work drops by one line compared with the version using an external return. Working range and electronics match the other size 27 versions with the E spool.
