Abstract
Seal ring assemblies for use with rotary valves and methods to manufacture the same are disclosed. A seal ring assembly is described that includes a ring-shaped seal to be fixed within the rotary valve, where the seal enables the sealing engagement of a control member with a flow control aperture. The seal is compressed between a first seal clamp and a second seal clamp by a compressive force maintained by a plurality of fasteners extending through the seal and fixed to the first and second seal clamps.
