Proportional Directional Valve 4WRZ25E325-7X/6EG24N9K4/D3V - Bosch Rexroth R900959579

If a large cylinder has to extend in a short time, rated flow must be high enough. The 4WRZ25E325-7X/6EG24N9K4/D3V delivers 325 l/min in size 25 and works with pilot oil supplied and returned externally.

Benefits

• Rated flow of 325 l/min in size 25, with up to 870 l/min across the valve.
• External 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 for commissioning without an electrical signal.
• 20.52 kg, FKM seals, operating pressure up to 350 bar, connection diagram ISO 4401-08-08-0-05.

Applications

The valve is used on lifting cylinders and press axes with a large volume per stroke. The rated flow of 325 l/min shortens travel time without putting a second valve in parallel. Spool symbol E defines how the ports are assigned.
