The AAFARS fuel hoses are connected to the fuel drums with valved elbow couplings, figure 12, with integral camlock
couplers. The valve handle operates a poppet valve which, when opened, unseats and holds open the spring-loaded inlet or
outlet valve in the fuel drum. Full travel (fully closed to fully open) requires approximately seven turns. When the poppet
valve is closed, the valve stem is extended; when open, it is retracted. The stem travel is opposite that of conventional valves
and requires the operator to double check valve position during system set up and tear down, since observation can be
misleading.
