Snubbing Back Pressure Valve
The Snubbing Back Pressure Valve was designed to provide a
dependable method of well control. This tool is typically run close
to the bottom of the string to prevent fluid or gas from entering the
tubing string. The dual flappers allow for a ball to pass through the
tool and are more reliable than old style ball checks or dart-type
floats.
