摘要： A wellbore servicing system comprising a valve comprising a housing comprising ports, and a sleeve slidably positioned within the housing and transitional from a first to a second position to a third position, when the sleeve is in the first position and the second position, the sleeves blocks fluid communication via the ports and, when in the third position the sleeve does not block such fluid communication, wherein application of a fluid pressure transitions the sleeve from the first to the second position, and a reduction in fluid pressure transitions the sleeve from the second to the third position, and a deactivatable locking assembly between the housing and the sliding sleeve and configured such that, when activated, the locking assembly inhibits movement of the sleeve toward the third position, and when deactivated, the locking assembly will not inhibit movement of the sliding sleeve toward the third position.

摘要： Disclosed herein is a segmented seat for use in wellbore servicing systems, comprising an annular- shaped seat with an upward facing surface for receiving an obturator, the seat defining a central passageway. The seat comprises one or more slots or passageways and, wherein at least one slot or passageway extends continuously between seat segments. The at least one slot or passageway contains a nonmetallic material suitable for retaining the segments together yet frangible or flexible enough to allow the segments to separate when forced to do so. The segments have gripping surfaces which prevent or inhibit rotation of the seat during removal.
