Proportional Directional Valve 4WRDE16V1-150L-6X/MXYWG/24A5 - Bosch Rexroth R901540809

Differential cylinders draw different amounts of oil on each side, so the choice of spool symbol decides how smoothly an axis runs. The 4WRDE16V1-150L-6X/MXYWG/24A5 applies symbol V1 with 150 l/min nominal flow in size 16, piloted externally and drained externally.

Benefits

• Symbol V1 in three switching positions, matched to axes with different oil demand per direction of travel.
• 150 l/min nominal flow with a maximum flow of 460 l/min.
• External pilot oil supply and external return, independent of the working pressure of the axis.
• Internal spool position feedback, command value ±10 V DC on a 24 V DC supply.
• Operating pressure up to 350 bar, NBR seals, weight 10.5 kg.

Applications

The valve drives feed and lifting axes with differential cylinders, for example in forming machines and lift tables. Symbol V1 compensates the area ratio so that extending and retracting run at comparable smoothness. The separate pilot circuit stays unaffected by load pressure.
