SEAL RING ASSEMBLIES FOR USE WITH ROTARY VALVES.

摘要

Seal ring assemblies for use with rotary valves and methods to manufacture the same are disclosed. A seal ring assembly (108) is described that includes a ring-shaped seal (112) 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 (114) and a second seal clamp (116) by a compressive force maintained by a plurality of fasteners (118) extending through the seal and fixed to the first and second seal clamps.
