Proportional Directional Valve 4WRKE32W6-600L-3X/6EG24EK31/A1D3V - Bosch Rexroth R901451903

Anyone wanting to avoid a dedicated pilot pump chooses internal pilot supply. The 4WRKE32W6-600L-3X/6EG24EK31/A1D3V takes pilot oil from working pressure, drains it through a dedicated Y channel and meters 600 l/min rated flow on a ±10 V command.

Benefits

• Internal pilot oil supply, a separate pilot pump is no longer needed
• External pilot oil return, which keeps the pilot stage free of back pressure
• 600 l/min rated flow, up to 1600 l/min maximum flow
• ±10 V command value, on-board electronics, 24 VDC supply
• Operating pressure up to 350 bar, port pattern ISO 4401-10-09-0-05, FKM seals
• Spool W6, linear characteristic curve, three switching positions, 37 kg

Applications

A fit for presses and forming lines with stable system pressure where no separate pilot circuit should be built. It assumes working pressure is high enough at start-up to feed the pilot stage. Where that is uncertain, the build with external supply is the right choice.

Manufacturer

Material number R901451903 at Bosch Rexroth, product family 4WRKE. The E in 6EG24EK31 marks the internal pilot supply, A1 the voltage command.
