Honoured at the SIPEC trade fair

The GEMÜ 650TL diaphragm valve
The GEMÜ 650TL diaphragm valve (PresseBox) (Ingelfingen-Criesbach, ) Last year at the SIPEC trade fair in Orléans (France), the Innovation Prize went to GEMÜ for the development of its innovative GEMÜ 650TL "safety valve".

If the flow velocity in a loop reduces, it can fall below a critical value. When the GEMÜ 650TL diaphragm valve is used, selected tapping points can automatically be closed by the central process monitoring system in order to reduce the tapping quantity and thus 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.

This optimisation adds to the reputation of the GEMÜ 650TL as a "safety valve", because the additional functionality further contributes to protecting plant operators and the conducted medium. Even if the valve closes due to the prevailing parameters (shutoff of control air) and the operator inadvertently forgets to close the hand wheel, uncontrolled escape of the medium can still be prevented.
