Dual-Flapper Check Valve

High-pressure cartridges prohibit fluid migration

For thru-tubing operations, the dual-flapper check valve prevents wellbore pressure or fluids from entering the workstring. This valve uses high-pressure cartridges that prohibit fluid migration and ensure workstring integrity. A large internal bore minimizes friction at high flow rates while providing a reliable seal against unwanted pressure and fluids typically encountered in thru-tubing operations. The dual-flapper check valve also has a spring activated for positive closure during inactivity and a redundant seal setup for increased safety.
