Proportional Directional Valve 4WRKE32R600L-3X/6EG24ETK31/A1D3M - Bosch Rexroth R900717028

Once size 32 is fixed, the spool symbol decides the control behaviour. The 4WRKE32R600L-3X/6EG24ETK31/A1D3M carries symbol R, feeds pilot oil in as well as back internally, and turns a ±10 V command value into 600 l/min of nominal flow.

Benefits

• Spool symbol R with a linear characteristic, the alternative to the R3 version of the same series.
• Internal pilot oil supply with internal return, no extra lines needed.
• 600 l/min nominal flow, peak figure 1600 l/min at up to 350 bar.
• Command value ±10 V, processed by the on-board electronics.
• NBR seals, 37.4 kg, connection diagram ISO 4401-10-09-0-05, four ports.
