Proportional Directional Valve 4WRZ32W6-520-7X/6EG24N9TK4/M - Bosch Rexroth R900249813

Some plants have a pilot pump but no separate return line. The 4WRZ32W6-520-7X/6EG24N9TK4/M matches that and controls 520 l/min nominal flow with external supply and internal return.

Benefits

• Pilot oil supplied externally, drained internally, matched to an existing pilot pump.
• 520 l/min nominal flow with spool symbol W6.
• 350 bar maximum operating pressure, flow up to 1600 l/min.
• 43.42 kg weight, NBR seals, size 32.
• Concealed auxiliary actuation, driven by external electronics.

Applications

The version suits plants that already have a pilot supply and route the return through the main circuit. That saves a line without making pilot pressure depend on the main channel. Dimensions and ratings are given in the series data sheet.
