Fully closed
2.
Half closed
3.
One quarter open

A relief valve is incorporated
into LOX systems to prevent
excessive pressure buildup. On
most LOX systems this relief
valve is set to open at
approximately how many psig?
10-40.
Additional protection against
over pressurization of a LOX
converter installed in an
aircraft is a relief valve
installed in the aircraft oxygen
plumbing.
