Description
Even in size 16 the pilot circuit can be routed internally when system pressure is stable enough. This version uses that and needs only the 4 main ports on the manifold for 180 l/min nominal flow at 350 bar.
Benefits
- 180 l/min nominal flow, up to 460 l/min maximum flow at 350 bar.
- Internal pilot oil supply and internal drain, no additional piping on the manifold.
- ISO 4401-07-07-0-05 interface, spool symbol W6, 3 switching positions.
- 4...20 mA command value on on-board electronics, concealed manual override.
- 12.5 kg weight, NBR seals, HL hydraulic fluid, UKCA under SI2016/1091.
Applications
Fits large lift and press axes whose system pressure stays largely constant across the cycle. Internal pilot routing simplifies the manifold noticeably. 180 l/min moves large cylinders in reasonable time.
Manufacturer
Bosch Rexroth, material number R901447945. Series part from current production. Data sheet RE 29115 and overview RE 07600-B carry all the ratings.
