Abstract: A ball valve includes valve seats surrounding a valve ball and a valve housing surrounding the valve seats. A central flow passage extends through the valve seats, the valve ball, and the valve housing. Seals are positioned between a non-vertical bottom wall of each valve seat and corresponding non-vertical end walls of the valve housing. When a fluid pressure is applied to the ball valve in a closed position, one of the valve seats moves away from the valve housing to disengage the seal from the corresponding non-vertical housing end wall. The valve seat's movement provides an equalizing flow passage between the valve seat and the valve housing and into an interior portion of the valve ball, thereby allowing for pressure equalization that prevents deformation of the valve ball. The valve housing is formed by valve seat carriers, a cavity in a valve sub, or a combination thereof.

Abstract: A bracket is described for clamping a mould to a supporting structure. The bracket includes a first part and a second part for attaching to the mould and to the supporting structure, respectively, or vice versa. The first and second parts are connected together and configured to provide constrained relative movement along a first axis to accommodate thermal expansion of the mould relative to the supporting structure in a first direction parallel to the first axis. The first and second parts of the bracket are connected via an articulated joint that allows the first and second parts to pivot relative to one another without moving the first axis such that the bracket can independently accommodate misalignments between the mould and the supporting structure.
