McCANNA specializes in floating trunnion mounted ball valves (TMBVs). With a heritage dating to 1870, the brand manufactured its first valve in 1954 and has since logged many decades of development in new materials, manufacturing processes and valve technology. In addition to world-class quality, durability and longevity, McCANNA offers one of the few lines of top-entry critical service ball valves on the market that enables complete repair access without the need for removal from the pipeline. As a result, McCANNA products are highly specified; many can be found on a broad range of customer approved manufacturer lists (AMLs). The brand is best known for its top-entry, wedge-seated ball valves, which are in use worldwide.
