Proportional Directional Valve 4WRKE27R3-500L-3X/6EG24EK31/A1D3M - Bosch Rexroth R901264931

In circuits with strongly varying system pressure the pilot stage can stall. The 4WRKE27R3-500L-3X/6EG24EK31/A1D3M therefore draws its pilot oil externally and stays operational while metering 500 l/min nominal flow at 270 bar operating pressure.

Benefits

• External pilot oil supply in the EK31 version keeps the valve controllable even at low pressure in port P.
• 500 l/min nominal flow and up to 1000 l/min maximum flow.
• A ±10 V command value at the on-board electronics, 24 VDC supply.
• Spool symbol R3 with three switching positions across four ports, ISO 4401-08-08-0-05 mounting pattern.
• Operating pressure up to 270 bar, 19.35 kg valve mass, NBR seals for HL hydraulic fluid.

Application

Intended for plants with accumulator operation or several consumers where pump pressure collapses. A separate pilot oil line has to be planned. Otherwise the valve remains interchangeable with the K31 version of the same series, since mounting pattern and size are identical.

Manufacturer
