Proportional Directional Valve 4WRZ10E1-85-7X/6EG24ETK4/M - Bosch Rexroth R900736895

Anyone who needs symbol E1 in a manifold without a pilot circuit reaches for the internal version. The 4WRZ10E1-85-7X/6EG24ETK4/M takes pilot oil from the pressure channel, returns it there and works at 85 l/min nominal flow.

Benefits

• Spool symbol E1 at 85 l/min nominal flow, up to 170 l/min in the main channel.
• Internal pilot supply and internal pilot drain, without separate lines to the pilot stage.
• 315 bar operating pressure on the ISO 4401-05-05-0-05 pattern, size 10.
• 7.74 kg including a concealed manual override.
• 24 VDC through external electronics, 7-pole (6 + PE) plug to EN 175201-804, NBR seals.

Technical data

Applications

It is used on press and feed axes of smaller power units where system pressure is high enough to supply the pilot stage as well. The concealed manual override allows the axis to be moved without electronics, for instance during commissioning or fault finding. Changing to another flow rating in the series is possible without altering the subplate.
