CFI Annular BOP

Control Flow Annular BOP’s are particularly qualified to meet the industry’s needs for simple and reliable protection. All Control Flow Annular BOP’s are equipped with a field replaceable wear plate bolted to the inner bottom face of the BOP head. This non-sealing wear surface prevents upward movement of the packing during closure. Further, the packing units are manufactured from high quality rubber material reinforced with flanged steel segments. A full range of annular sizes and pressure ranges are offered in this reliable, time proven design.
