Calder, a long time producer of industrial valve testing equipment for heavy industry, has introduced its first portable valve testing system.  Now, refineries, treatment plants or any other facility with the need to control high pressure liquid, can test the valves on site, rather than having the valves shipped to a testing facility.  This makes a huge difference especially for facilities located far from civilization.
