Abstract
A wellbore control device includes a housing defining a throughbore which can receive a tubular, a first gate with a first hole, and a second gate with a second hole. The first gate and the second gate are supported by the housing and and can perform a movement transverse to the throughbore between an open position and a closed position. The movement of the first gate and the second gate from the open position to the closed position splits the throughbore into an upper portion and a lower portion, the upper position and the lower positing being completely separate from each other. The first hole and the second hole are aligned substantially co-axially with the throughbore in the open position. A part of at least one of the first hole and the second hole remains aligned with the throughbore in the closed position.
