Proportional Directional Valve 4WREE10W1-75-3X/M/24F1 - Bosch Rexroth R901582118

Frequency inverters and long cable trays couple noise into analogue lines, and a 4...20 mA current signal takes that far more calmly than a voltage. The 4WREE10W1-75 uses exactly this input, carries 75 l/min nominal flow, passes up to 180 l/min maximum flow and works at up to 350 bar. The relieved centre of symbol W1 keeps the axis unpressurised at standstill.

Benefits

• 4...20 mA command value, resistant to coupled interference and voltage drop
• 75 l/min nominal flow, up to 180 l/min maximum flow
• Spool symbol W1 with a relieved centre, four ports, three switching positions
• NBR seals for HL hydraulic fluid, 7.32 kg unit weight
• Operating pressure up to 350 bar, hole pattern ISO 4401-05-04-0-05
• On-board digital electronics, 24 VDC, 7-pole connector (6 + PE) to EN 175201-804

Application

The valve suits axes in electrically noisy surroundings, for example next to inverter cabinets, welding plant and large drives. A broken wire shows up as a reading below 4 mA and can be evaluated by the controller. The relieved centre also lowers power loss at standstill.
