Abstract
A connector link for use in an actuation system for a butterfly valve has a central web extending between two generally cylindrical ends. There are bores formed in each of two generally cylindrical ends and bushings extend axially upwardly from a nominal face at each of the ends. One of the ends has a bore formed at a radius defined as a first distance. A distance between center points of the bores in the first and second ends is defined as a second distance. The ratio of the second distance to the first distance is greater than or equal to 19.2772 and less than or equal to 19.4125. A valve and method are also disclosed.
