Proportional Directional Valve 4WRKE27R3-500L-3X/6EG24K31/F1D3M - Bosch Rexroth R901464400

Large cylinders lose cycle time as soon as the valve becomes the bottleneck. The 4WRKE27R3-500L-3X/6EG24K31/F1D3M therefore releases 500 l/min nominal flow and passes up to 1000 l/min at peak, at 270 bar operating pressure and under a 4...20 mA current command.

Benefits

• 500 l/min nominal flow and up to 1000 l/min maximum flow in size 27.
• A 4...20 mA current command stays stable over long cables and shows a broken wire as a reading below 4 mA.
• Spool symbol R3 with three switching positions across four ports, ISO 4401-08-08-0-05 mounting pattern.
• On-board electronics inside the valve, 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
• Operating pressure up to 270 bar at 18 kg valve mass, NBR seals for HL hydraulic fluid.

Application

Intended for presses, forging manipulators and large test rigs with high oil demand. A current command suits installations where cabinet and valve are far apart. Fitting and replacing the 18 kg assembly calls for a subplate rated accordingly.

Manufacturer

Bosch Rexroth lists this valve under material number R901464400. In the K31 version both pilot oil supply and pilot oil drain are routed internally.
