Proportional Directional Valve 4WRZ25E325-7X/6EG24N9EK4/D3V - Bosch Rexroth R900948083

High flow at a manageable mass makes mounting and handling on the manifold easier. The 4WRZ25E325-7X/6EG24N9EK4/D3V weighs 18.2 kg, meters 325 l/min of rated flow and returns its pilot oil externally.

Benefits

• Rated flow of 325 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.
• Pilot-operated main stage in size 25, with up to 870 l/min through the housing.
• 18.2 kg, FKM seals, operating pressure up to 350 bar, connection diagram ISO 4401-08-08-0-05.

Applications

This combination is wanted on axes with a high oil demand whose return line is pressurised. The external return decouples the pilot stage from back pressure in the tank channel. Spool symbol E covers the standard port assignment.
