Description
A valve that needs no external pilot lines yet still carries a pressure reducing valve in the pilot circuit simplifies the manifold and keeps switching time constant. Nominal flow is 85 l/min and operating pressure 315 bar.
Benefits
- 85 l/min nominal flow, up to 170 l/min maximum flow.
- Internal pilot oil supply and internal drain, the 4 main ports are all that is piped.
- Pressure reducing valve in the pilot circuit, giving consistent switching times at 315 bar.
- Concealed manual override, ±10 V command value, 24 V DC supply.
- 8.49 kg weight, spool symbol W8, NBR seals, ISO 4401-05-05-0-05 interface.
Applications
The classic case for machine tools and handling equipment without a separate pilot circuit. The valve replaces an older unit directly on an existing standard subplate. At 85 l/min rapid and working strokes are covered from one stage.
Manufacturer
Bosch Rexroth, material number R900979517. Genuine series part. Further details are in data sheet RE 29115 and in overview RE 07600-B.
