Proportional Directional Valve 4WRZ25E220-7X/6EG24N9ETK4/D3V - Bosch Rexroth R900948085

When converting a manifold there is rarely room for new bores. The 4WRZ25E220-7X/6EG24N9ETK4/D3V therefore uses the existing P and T channels for its pilot stage and meters 220 l/min of rated flow.

Benefits

• Rated flow of 220 l/min in size 25, with up to 870 l/min across the valve.
• Internal pilot oil supply and internal pilot oil return on the pilot-operated main stage.
• Spool symbol E with three switching positions across four ports.
• Integrated pressure reducing valve in the pilot path for repeatable switching behaviour.
• 20.38 kg, FKM seals, operating pressure up to 350 bar, connection diagram ISO 4401-08-08-0-05.

Applications

The application lies in standard cases where tank pressure stays low and no separate pilot supply is needed. Together with the amplifier card, acceleration and deceleration can be set separately.
