Proportional Directional Valve 4WRZE25W6-325-7X/6EG24N9ETK31/F1D3V - Bosch Rexroth R900948609

Frequency converters and long drag chains disturb voltage signals reliably. This valve therefore accepts 4-20 mA, works with spool symbol W6 and meters 325 l/min nominal flow without any external pilot lines at all.

Benefits

• 4-20 mA current interface, robust against pick-up from frequency converters and motor cables
• 325 l/min nominal flow, operating pressure up to 350 bar
• Pilot circuit entirely internal, no X and no Y line required
• Spool symbol W6, three switching positions, four ports
• Mass 20.54 kg, on-board electronics at 24 VDC

Application

The current interface makes sense on moving machine parts and in plants packed with converters, for example on handling axes and gantries. The internal pilot circuit keeps hose routing on the moving axis slim. The requirement for low tank pressure on the return still applies.

Manufacturer
