Award winning ‘safety’ valve from GEMÜ

If the flow velocity in a loop reduces, it can fall below a critical value.

But when the GEMÜ 650TL diaphragm valve is used, selected tapping points can automatically be closed by the central process monitoring system to reduce the tapping quantity and increase the flow velocity.

The GEMÜ 650TL "safety valve" was last year awarded a prestigious Innovation Prize at the SIPEC trade fair in Orléans, France.

With the GEMÜ 650TL 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.
