Proportional Directional Valve 4WRTE16W6-150L-4X/6EG24EK31/F1V - Bosch Rexroth R901529955

A backed up return distorts the behaviour of the pilot stage. The 4WRTE16W6-150L-4X/6EG24EK31/F1V therefore leads the pilot return separately to the outside while still taking pilot oil internally, at 150 l/min nominal flow and up to 350 bar.

Benefits

• The external pilot return stays unaffected by back pressure in the tank channel.
• Internal pilot oil supply saves an additional pressure line.
• FKM seals for installations whose specification rules NBR out.
• 150 l/min nominal flow, spool symbol W6, mounting pattern ISO 4401-07-07-0-05.
• 4...20 mA command, 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804, 11.08 kg.

Applications

The valve suits installations with return filters, coolers or long tank lines where measurable pressure builds in the return. Routing the pilot return separately keeps the pilot stage clear of it. A nominal flow of 150 l/min covers lifting and clamping axes of medium size.
