An access bore intersects the cavity and has a support shoulder formed in it. A holder is supported on the support shoulder. A flapper is pivotally secured to the holder and located in the cavity for movement between an open position and a closed position blocking flow through the seat. A straight edge portion in the access bore engages a straight edge portion of the holder to prevent rotation of the holder.
