Proportional Directional Valve 4WRKE25R3-350L-3X/6EG24K31/A1D3M - Bosch Rexroth R901201717

A linear characteristic makes tuning the superimposed controller predictable. The 4WRKE25R3-350L-3X/6EG24K31/A1D3M works with spool symbol R3 and a linear curve, handling 350 l/min nominal flow at operating pressures up to 350 bar.

Benefits

• Linear characteristic with spool symbol R3, metering area follows the command value evenly.
• 350 l/min nominal flow, up to 870 l/min maximum flow, operating pressure up to 350 bar.
• External pilot oil supply and external return, the pilot stage runs on its own pressure.
• Internal spool position feedback, plus/minus 10 V command value, 24 VDC supply voltage.
• Three switching positions on four ports, ISO 4401-08-08-0-05 interface.
• 19.94 kg, NBR seals, 7-pole connector (6 + PE) to EN 175201-804.

Application

The valve suits position controlled cylinder axes in presses, testing machines and forming lines. The external pilot circuit has to carry pressure even when the main circuit is unloaded. NBR seals assume operation on mineral oil.
