The pilot oil arrangement decides how the manifold is piped. This version takes pilot oil from outside and drains it internally, works without a pressure reducing valve in the pilot circuit and controls 50 l/min nominal flow at 315 bar.
Benefits
- 50 l/min nominal flow, up to 170 l/min through the size 10 body.
- External pilot oil supply with internal pilot oil drain, so only one extra line reaches the manifold.
- No pressure reducing valve in the pilot circuit, rated for 315 bar system pressure.
- FKM seals instead of NBR, ±10 V command value on on-board electronics.
- 8.48 kg weight, spool symbol W8, ISO 4401-05-05-0-05 interface.
