Proportional Directional Valve 4WRTE16V220L-4X/6EG24EK31/F1V - Bosch Rexroth R901552944

The 4WRTE16V220L-4X/6EG24EK31/F1V takes its pilot oil internally from the main circuit but returns it to tank through a dedicated Y line. That keeps the pilot stage free of return pressure even when several consumers drain at the same time. Spool symbol V opens linearly at 220 l/min nominal flow, with peaks to 460 l/min.

Benefits

• Internal pilot supply with external return through Y, independent of tank pressure.
• Spool symbol V with a linear curve, 220 l/min nominal flow, 460 l/min maximum.
• Operating pressure to 350 bar in size 16.
• 4...20 mA command input at the on-board electronics with closed loop spool control.
• FKM seals, 11.08 kg, mounting pattern ISO 4401-07-07-0-05.

Application

The valve belongs in plants with long shared return lines, for example presses and test rigs running several axes in parallel. Mineral oil of class HL is intended. Control runs through a 7-pole plug to EN 175201-804 on 24 VDC.
