An embodiment uses a symmetrical elastomeric design with hydraulic pistons on either end (as opposed to a single piston on conventional BOPs) which allows for lower actuation forces, reduced friction, and reduced wear and tear. The lower actuation forces correspond to lower operating pressures which allows the body and housing to be smaller, leading to a smaller footprint.

Annular blow out preventer

Embodiments include a choke system that passes enlarged debris despite having a relatively small diameter for an input port of the choke system. Embodiments also include systems to prevent dislodging of a choke seat when backpressure is supplied to the choke system. Embodiments also include sealing systems to prevent fluid leaks around the choke seat of the choke system.
