Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9EK31/A1V - Bosch Rexroth R900935675

A slewing drive stands still most of the time, and during those hours no residual pressure should strain the pilot stage. The 4WRZE10W6-85-7X/6EG24N9EK31/A1V therefore routes its pilot drain separately to the outside and meters 85 l/min nominal flow at operating pressures up to 315 bar.

Benefits

• Internal pilot oil supply with external pilot oil return, pilot stage relieved while at rest.
• 85 l/min nominal flow, maximum flow 170 l/min in size 10.
• Spool symbol W6, 3 switching positions and 4 ports.
• ±10 V command value on the on-board electronics, 24 VDC on a 7-pole (6 + PE) connector to EN 175201-804.
• Operating pressure up to 315 bar, connection diagram ISO 4401-05-05-0-05, 11 kg weight.
• FKM seals for HL hydraulic fluid.

Applications

The valve is used on slewing gear, rotary tables and flap drives with long holding phases. Its separate pilot drain keeps the pilot stage unpressurised even while other axes work into the shared return. At 85 l/min the swivel motion can be started and stopped gently.
