Overview
Towards the bottom of the assembly a check valve is needed to allow circulation though liner while preventing flowback. The Float Collar is a back up check valve to the float shoe. During the cementing process, high external annular pressure is created. Check valve/s in the float collar prevent cement from flowing back into the liner. Additionally, the check valve prevents well pressure kicks from returning up the drill pipe
