Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9K31/F1D3V - Bosch Rexroth R900705328

Twenty metres of cable between controller card and valve are normal in plant engineering. The 4WRZE10W6-85-7X/6EG24N9K31/F1D3V therefore takes its command value as a 4 to 20 mA current signal on its on-board electronics and meters 85 l/min nominal flow at operating pressures up to 315 bar.

Benefits

• Command value 4 to 20 mA, the current loop stays readable over long cable runs.
• 85 l/min nominal flow, 170 l/min at peak, operating pressure up to 315 bar.
• External pilot oil supply and external pilot oil return separate the pilot stage from the main circuit.
• The built-in pressure reducing valve keeps pilot pressure independent of system pressure.
• Spool symbol W6, three switching positions on four ports, ISO 4401-05-05-0-05 interface.
• 8.42 kg, FKM seals, 7-pole connector (6 + PE) to EN 175201-804, UKCA conformity.

Technical data

Application

The valve is intended for cylinder and motor axes in presses, injection moulding machines and test rigs that already run a central pilot oil supply. An external pilot circuit pays off where main pressure fluctuates strongly. The current interface matches controller cards with a 4 to 20 mA output.
