Proportional Directional Valve 4WRZ25W8-325-7X/6EG24ETK4/D3M - Bosch Rexroth R901015955

The fewer pilot lines a machine needs, the simpler its piping becomes. The 4WRZ25W8-325-7X works in size 25 entirely without an external pilot circuit and still meters 325 l/min nominal flow through spool symbol W8.

Benefits

• Pilot oil fed in and drained internally, neither an X nor a Y line has to be laid.
• 325 l/min nominal flow, up to 870 l/min peak flow in size 25.
• Spool symbol W8 with 3 switching positions across 4 ports on the ISO 4401-08-08-0-05 interface.
• Integrated pressure reducing valve for constant pilot pressure at 350 bar system pressure.
• 20.48 kg weight, NBR seals, commanded at 24 VDC through external electronics.

Applications

The valve suits presses and lifting gear where a separate pilot supply is unwanted. Because the pilot stage feeds from the main channel, the four working ports of the subplate are enough. The amplifier card stays in the cabinet and connects through the 7-pole plug.
