Proportional Directional Valve 4WRZE10W8-50-7X/6EG24ETK31/A1M - Bosch Rexroth R901245658

A nominal flow that is too large pushes the control into a narrow section of the characteristic. The 4WRZE10W8-50-7X/6EG24ETK31/A1M is therefore graded at 50 l/min and uses the full spool travel across the whole range, with spool symbol W8.

Benefits

• 50 l/min nominal flow in size 10.
• Spool symbol W8 with three switching positions and four ports.
• Command value ±10 V through on-board electronics at 24 V DC.
• Internal pilot oil routing for supply and return.
• 315 bar maximum operating pressure at 7.99 kg weight, UKCA to SI2016/1091.

Applications

The grade suits smaller feed, clamping and positioning axes where resolution matters more than throughput. Connection diagram ISO 4401-05-05-0-05 stays the same, so changing the grade does not change the piping. The hydraulic fluid is HL.
