Proportional Directional Valve 4WRTE32E600P-4X/6EG24ETK31/F1M - Bosch Rexroth R901445270

Twenty metres of cable often run between the control cabinet and the press manifold, right next to frequency converters. The 4WRTE32E600P-4X/6EG24ETK31/F1M therefore uses a 4 to 20 mA current command and provides 600 l/min nominal flow at 350 bar.

Benefits

• 4 to 20 mA current command, insensitive to voltage drop and interference on long cables.
• 600 l/min nominal flow in size 32, flow capability up to 1600 l/min.
• Symbol E with linear characteristic and fine control range, internal spool position feedback.
• Internal pilot oil supply and return, so the main subplate ports are sufficient.
• 36 kg weight, the lightest valve of this series in the range.
• 350 bar operating pressure, 24 V DC, 7-pole connector (6 + PE) to EN 175201-804.

Technical data

Application

The current input pays off in forming presses, rolling mills and foundries where cable routes are long and drives radiate noise. With the pilot stage fed internally, piping is limited to P, T, A and B. In return, working pressure has to stay above the minimum pilot pressure at all times.
