Proportional Directional Valve 4WRZE10E1-85-7X/6EG24ETK31/A1M - Bosch Rexroth R900749718

When the main circuit carries enough pressure at all times, internal piloting is the simplest solution. The 4WRZE10E1-85-7X/6EG24ETK31/A1M uses it for supply and return and controls 85 l/min nominal flow with spool symbol E1.

Benefits

• Internal pilot oil supply and return, four ports are enough at the manifold.
• 85 l/min nominal flow in size 10, up to 170 l/min maximum.
• Spool symbol E1 with three switching positions.
• Command value ±10 V through on-board electronics at 24 V DC.
• 8.09 kg weight, 315 bar maximum operating pressure, UKCA to SI2016/1091.

Applications

This variant covers the standard case on machine tools, presses and test benches whose system pressure stays stable. Fewer lines mean fewer fittings and a shorter commissioning. The seals are NBR and the intended hydraulic fluid is HL.
