Proportional Directional Valve 4WRTE16V1-150L-4X/6EG24ETK31/F1M - Bosch Rexroth R901416677

A compact power unit often has only one pump, and a second one for the pilot circuit fits neither the space nor the budget. The 4WRTE16V1-150L-4X/6EG24ETK31/F1M does without: pilot oil is taken internally and returned internally, at 150 l/min nominal flow and up to 350 bar.

Benefits

• Internal pilot oil supply and internal return make a separate pilot pump unnecessary.
• 150 l/min nominal flow in size 16, series up to 460 l/min.
• 4...20 mA command and 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
• Spool symbol V1, 3 switching positions, mounting pattern ISO 4401-07-07-0-05.
• NBR seals for HL fluid, weight 11.3 kg.

Applications

Typical applications are compact power units, mobile test equipment and auxiliary axes of larger machines. Because both pilot paths run internally, piping is reduced to the four working ports of the subplate. That also cuts the number of possible leak points.
