Carleton's Riser Line Shut-Off Valve is an integral part of an aircraft's gaseous passenger
emergency oxygen system. The valve, or flow fuse, serves to isolate a section of the emergency
oxygen system in the event of a severed distribution line. The flow fuse activates when the oxygen
flow exceeds the normal operating levels. By isolating the damaged section, the remaining areas of
the emergency system remain operational.
Carleton's low profile Riser Line Shut-Off Valve has been qualified for use and is original equipment (OEM) on large commercial aircraft.
Features:
The Riser Line Shut-Off Valve features a self-centering, floating seat design. The valve can flow up
to 264 slpm to the downstream masks without closing. A damping ullage provides protection
against closure during the centralized flow control unit surge function.
The valve design maximizes oxygen safety while providing reliable, high performance operation.
