Proportional Directional Valve 4WRZ25W6-325-7X/6EG24N9K4/D3V - Bosch Rexroth R900957451

When a fast axis calls for a symbol with different control edge ratios, W6 is the choice. The 4WRZ25W6-325-7X/6EG24N9K4/D3V brings that symbol together with 325 l/min of rated flow and runs a fully external pilot oil circuit.

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 W6 with three switching positions across four ports.
• External electronics, the card stays in the cabinet and is reachable without removing the valve.
• 20.36 kg, FKM seals, operating pressure up to 350 bar, connection diagram ISO 4401-08-08-0-05.

Applications

Valves like this control axes that travel at high flow and still have to position finely. The external pilot circuit can be built with its own filter and its own pressure stage. Closed loop control sits on an amplifier card outside the valve.
