Filter Separator Rate of Flow/Shut-Off Valve 

The filter separator rate of flow shut-off valve shall open and close via hydraulic signals from the interface float pilot, and shall limit the flow rate through the filter separator to a predetermined maximum.

The OCV 119-5 has a very specific purpose: to limit the flow of fuel through a filter separator, and to close fully in the event of high water levels in the filter separator sump. To perform this task, it must operate in conjunction with one of the OCV 800 series interface float pilots.
