Proportional Directional Valve 4WRZE32W9-520-7X/6EG24N9ETK31/A1D3M - Bosch Rexroth R901201549

When rebuilding a large manifold, every line saved counts. The 4WRZE32W9-520-7X takes pilot oil internally and returns it internally, so the X and Y ports fall away, while metering 520 l/min nominal flow at up to 350 bar.

Benefits

• Internal pilot supply and internal return, X and Y lines are not required.
• Nominal flow of 520 l/min, maximum flow 1600 l/min.
• Spool symbol W9 with three switching positions across four ports.
• Pressure reducing valve in the pilot stage for steady pilot pressure.
• Voltage command ±10 V, concealed manual override for setup work.
• Mass of 65 kg, connection diagram ISO 4401-10-09-0-05, NBR seals.

Application

Size 32 sits on main axes of presses, on die cushions and on lift cylinders of heavy machines. The 65 kg call for lifting aid during installation, and the manifold has to carry that mass permanently. Internal pilot routing keeps the connection down to four lines.
