Data Sheet

CFI BOP Units Produced

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.
