Further development: GEMÜ 650TL diaphragm valve

Video only available in German! GEMÜ product manager Marie-Luise Lederer presented the GEMÜ 650TL "safety valve" with its new feature at TechnoPharm 2014 in the "Rote Couch Express" technology talk. If the flow velocity in a loop reduces, it can fall below a critical value. The GEMÜ 650TL diaphragm valve can be used to specifically close tapping points automatically via the central process monitoring system in order to reduce the tapping quantity and thus to increase the flow velocity. It is now also possible to query the position of the handwheel. In this case, the position "handwheel closed" is detected by an optionally available proximity switch and communicated to the plant control system. Previously, this was only possible for the piston position of the actuator. Due to this improvement, a visual check of the plant in person is no longer absolutely essential. The position "handwheel closed" can be checked simply and conveniently from the control room. The animation explains how the diaphragm valve works.
