Proportional Directional Valve 4WRZE10W8-25-7X/6EG24N9EK31/A1V - Bosch Rexroth R901004131

A rotary table with large inertia depends on the fine resolution of the valve when it starts to move. The 4WRZE10W8-25-7X/6EG24N9EK31/A1V works there at 25 l/min rated flow, takes up to 315 bar and draws pilot oil internally while returning it externally.

Benefits

• 25 l/min rated flow, which gives fine resolution of the command signal at start.
• Spool symbol W8 blocks at centre, three switching positions, operating limit 315 bar.
• Internal pilot oil supply with external pilot oil return, without a pressure reducing valve.
• Command value 10 V bipolar into the on-board electronics, 24 VDC supply.
• Concealed manual override, 8.48 kg, size 10 to ISO 4401-05-05-0-05, FKM seals.

Application

Rotary tables, indexing units and slewing gear with large inertia use this control for the acceleration and braking ramp. The external pilot oil return keeps tank line back pressure away from the pilot stage. For higher travel speed, 50 and 85 l/min are available.
