NOTES:
Above performance data refer to valves coupled with Atos electronic drivers, see section 2
The flow regulated by the directional proportional valves is not pressure compensated. Thus it is affected by the load variations. To keep costant the regulated flow under different load conditions, modular pressure compensators are available (see tab. D150)
For different P, the max flow is in accordance to the diagrams in sections 14.2 and 15.2
