Parker Instrumentation has published a free guide to its instrumentation ball valve family for instrument and process applications, the Hi-Pro family. Featuring a novel two-piece construction that reduces potential leak paths to a minimum, the 10,000PSI valves are suitable for long-lifecycle applications. Available in four basic bore sizes of 10, 15, 20 and 25mm, the application scope for these Parker valves spans areas such as isolation on process lines, vessel draining and venting, and hydraulic applications. The free 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. This new guide is also available for download via the website.
