Proportional Directional Valve 4WRZE10W8-85-7X/6EG24ETK31/F1D3V - Bosch Rexroth R901040923

A current signal has one practical edge over a voltage: if it drops below 4 mA, the fault is unambiguous. The F1D3V version of the 4WRZE10W8-85-7X is commanded that way and meters 85 l/min nominal flow at 315 bar.

Benefits

• Command value 4 to 20 mA - a broken wire or lost signal shows up at the current threshold.
• Symbol W8, 3 switching positions, 4 ports, mounting pattern ISO 4401-05-05-0-05.
• 85 l/min nominal flow at 315 bar operating pressure, up to 170 l/min.
• Pressure reducing valve in the pilot circuit, internal supply and internal drain.
• 9.1 kg, FKM seals, UKCA to SI2016/1091, HL hydraulic fluid.

Application

A fit for plant with diagnostic requirements, where a lost command value has to be detected reliably. Against the voltage version of the same valve only the interface changes, the hydraulics and the symbol stay identical. The controller has to provide a current output with sufficient burden capability.
