Valve seating with electrodes, especially for <<enamel-test>> type control device

摘要

A valve seating (23) is made from a fluoridated polymer, for example, solid glass-coated PTFE or reinforced PFA. It comprises at least one electrode (24) attached to or integral with said seating and made of conductive material that is compatible with the seating, for example, graphite-Teflon. The valve seating according to the invention is especially for use in conjunction with a device for verifying the integrity of an enamel coating, of the <> type. The seating is then used on the waste valve (11) of the container to be checked and it comprises two electrodes (24) disposed so as to be in contact with the contents (8). This invention is of interest to the chemical industry, particularly manufacturers and users of <> devices.
