Proportional Directional Valve 4WRZE25W8-325-7X/6EG24ETK31/F1D3M - Bosch Rexroth R900720627

In rolling mills and foundries electrical fields and long cable runs disturb any voltage command. The 4WRZE25W8-325-7X/6EG24ETK31/F1D3M therefore works from a 4 ... 20 mA current signal and meters 325 l/min nominal flow at 350 bar with it.

Benefits

• A 4 ... 20 mA current command stays stable next to large drives and along long cable routes.
• 325 l/min nominal flow, 870 l/min maximum, for large cylinders on short cycle times.
• Internal pilot oil supply and internal pilot oil return avoid extra lines in a hot environment.
• The integrated pressure reducing valve holds pilot pressure steady regardless of system pressure.
• Spool symbol W8, three switching positions, four ports, mounting pattern ISO 4401-08-08-0-05.
