REVERSE CIRCULATING FLAPPER CHECK VALVE

The LiMARĀ® Reverse Circulating Flapper Valve is designed specifically for reverse circulating operations in order to provide a positive double barrier to protect the CT string from invasion of well- bore fluids.

The tool is configured so that the flapper valves are held open during normal operations thus allowing circulation from the annulus to the Coiled Tubing string. In the event of an emergency, or as part of the planned work-scope, a drop ball can be launched to shift a piston which activates the flapper valves to provide a positive barrier from well-bore fluids.
The cartridge type design allows fast and efficient redress with simple removal and replacement of the flapper cartridge assembly at surface.
