Proportional Directional Valve 4WRDE16V1-220L-6X/MXYWG/24A5 - Bosch Rexroth R901490893

When an axis with unequal piston areas also has to travel fast, spool symbol and nominal flow must match. The 4WRDE16V1-220L-6X/MXYWG/24A5 brings symbol V1 and 220 l/min nominal flow together in size 16, with a separated pilot circuit.

Benefits

• Symbol V1 compensates the area ratio of a differential cylinder across three switching positions.
• 220 l/min nominal flow, 460 l/min maximum, leaving reserve for rapid traverse phases.
• External pilot oil supply and external return, independent of load pressure at the axis.
• Internal position feedback, command value ±10 V DC, supply 24 V DC through a 7-pole connector (6 + PE).
• Operating pressure up to 350 bar, weight 10.5 kg, NBR seals, mounting pattern ISO 4401-07-07-0-05.

Applications

Target applications are lifting axes, tilting units and feeds in forming lines that travel fast yet have to decelerate gently. The high nominal flow allows short cycle times without pushing control to its limit. An external pilot circuit keeps piloting stable even at low working pressure.
