Proportional Directional Valve 4WRZ25E220-7X/6EG24N9EK4/D3V - Bosch Rexroth R900949223

When laying out a manifold, every kilogram hanging on the bracket counts. The 4WRZ25E220-7X/6EG24N9EK4/D3V weighs 18.2 kg, meters 220 l/min of rated flow and takes its pilot oil internally with an external return.

Benefits

• Rated flow of 220 l/min in size 25, with up to 870 l/min across the valve.
• Internal pilot oil supply and external pilot oil return on the pilot-operated main stage.
• Spool symbol E with three switching positions across four ports.
• Concealed auxiliary actuation that lets the axis be moved without control voltage.
• 18.2 kg, FKM seals, operating pressure up to 350 bar, connection diagram ISO 4401-08-08-0-05.

Applications

The valve is used on feed axes whose tank channel carries back pressure. Spool symbol E assigns the four ports for the standard case. External electronics make it possible to store ramps and characteristic curves in the card.
