Proportional Directional Valve 4WRLE27W8-430LJ-4X/MXY/24F1 - Bosch Rexroth R901551480

Over long cable runs a current loop is the more robust choice. The 4WRLE27W8-430LJ-4X/MXY/24F1 takes its command value as 4 to 20 mA and turns it into 430 l/min nominal flow, at up to 1850 l/min maximum flow.

Benefits

• Command value 4 to 20 mA, a broken wire shows up in the signal itself.
• 430 l/min nominal flow in size 27, up to 1850 l/min flow.
• Symbol W8 with a defined overlap, three switching positions.
• 270 bar operating pressure, connection diagram ISO 4401-08-08-0-05.
• External pilot oil supply plus external return, constant pilot pressure.
• 20.12 kg, NBR seals, CE conformity, on-board electronics.

Applications

The valve suits sprawling plants where cabinet plus valve manifold sit dozens of metres apart. A current loop stays stable there, and a cable fault produces a recognisable signal rather than a seemingly valid zero.
