Parker Instrumentation has published a guide to its instrumentation ball valve family for instrument and process applications, Hi-Pro. Featuring a two-piece construction that reduces potential leak paths to a minimum, the 10,000lb/in2/689 bar valves are suitable for long-lifecycle applications. Available in four basic bore sizes of 10, 15, 20 and 25mm, the application scope for Parker’s valve is very wide and spans areas such as isolation on process lines, vessel draining and venting, and hydraulic applications. The guide details valve specifications, and the range of configuration possibilities such as the choice of end connections, providing users with 42 valve options in total.
