Abstract

La présente invention concerne des systèmes et des unités permettant de couper le gaz. Dans un mode de réalisation, une unité d'arrêt de gaz est conçue pour être montée sur une soupape de commande de gaz sans contact direct avec un fluide ou un gaz disposé à l'intérieur de celle-ci. L'unité d'arrêt de gaz comprend un émetteur conçu pour recevoir un signal qui peut amener l'unité d'arrêt de gaz à pousser la soupape de commande de gaz vers une position fermée.
