The stopper can be actuated manually from the cabinet or by remote control after it receives a signal from a pH probe or fire alarm.
The system offers numerous advantages in terms of installation and operation.
It’s installation requires no major civil engineering works.
The control cabinet is designed to inflate the stopper in a few seconds.
The control panel is connected to a nitrogen bottle present in the cabinet to ensure his independency. For the deflation of the stopper the control panel is equipped with a high flow venturi.
Stoppers are available for pipes of all diameters, ranging from 100 to 2,000 mm and more
