ARD-BF-009 engineering requirements
Engineering data	Configuration requirement
Hydraulic system	Specify working pressure, fluid, supply/return interfaces and the location of the power unit.
Motion and emergency duty	Confirm load, speed control, accumulator requirements, manual override and the required loss-of-pressure action.

The illustration does not include a hydraulic power unit. Accumulators, emergency energy storage and fail action are project selections.

Confirm cover-removal clearance, disc extraction route, weld procedure and the approved outline drawing.

Published ratings do not establish suitability for every listed medium. Oxygen cleaning, material compatibility, trapped-liquid relief and project approvals are specified for the selected assembly. Liquid-hydrogen and helium service require a separate temperature and material review.
