Description: The manufacture of sleuce values at Glenfield and Kennedy Ltd., Kilmarnock. Traces their production from the design stage through casting, forging, and assembly, to subsequent testing. This film gives a clear overview of all the work carried out at Glenfield's. Glenfield's sleuce valves were in high demand all over the world, and were used for many varied industrial processes: they're everywhere!

James Nasmyth was the engineer responsible for the invention of the sleuce valve.
