Abstract
A seat assembly (28) for a valve member (20) includes a seat carrier (40) defining a pocket to receive a rigid seat ring (42). The outer peripheral surface (56) of the rigid seat ring (42) is spaced radially from the inner peripheral surface (45) of the seat carrier (40) to define a radial clearance therebetween of at least around 0.001 inch per inch of flow passage diameter. The sealing surface (58) of the seat ring (42) extends at 45 degrees to the longitudinal axis of the flow passage and the flexing and expansion of rigid seat ring (42) when the valve member (20) is moved to closed position permit the seat ring (42) to conform to irregularities in the adjacent mating sealing surface.
