Abstract
A floating ball valve has a metal multiple component seat installed in the seat pocket. The multiple component seat further includes a support ring and at least one seal element. The support ring and the seal element are juxtaposed and both are adjacent to the ball when the floating ball valve is in a closed position. The support ring is in a overlapping complimentary position with respect to the seal element, the seal element having greater elasticity than the support ring and the support ring having a greater load bearing strength than the seal element.
