Proportional Directional Valve 4WRTE25V220L-4X/6EG24ETK31/F1M - Bosch Rexroth R901417524

In plants with long cable routes the signal format decides how well interference is shrugged off. The 4WRTE25V220L-4X/6EG24ETK31/F1M therefore reads a 4 to 20 mA current signal and meters 220 l/min nominal flow at operating pressures up to 350 bar.

Benefits

• Command value 4 to 20 mA, the current loop stays readable over long distances.
• 220 l/min nominal flow, up to 870 l/min maximum flow, operating pressure up to 350 bar.
• Internal pilot oil supply and internal return, no additional lines on the manifold.
• Internal spool position feedback, spool symbol V with a linear characteristic.
• Three switching positions on four ports, ISO 4401-08-08-0-05 interface.
• 18 kg, NBR seals, 7-pole connector (6 + PE) to EN 175201-804.

Application

The valve is intended for position controlled axes in presses, test rigs and forming machines. Internal pilot supply saves plumbing but calls for sufficient system pressure. NBR seals assume mineral oil as the hydraulic fluid.
