ARD-BV-016 engineering requirements
Engineering data	Configuration requirement
Seat and relief arrangement	Confirm pressure direction, seat/seal materials and cavity pressure relief for the selected medium.
Integration	Confirm operator load, maintenance clearance, end standard and approved outline.

The NPS span is used because a published DN equivalent is inconsistent. Request the exact bore and connection dimensions.

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.
