Ils ne fonctionnent pas en l'absence de flux et dans les circuits en impasse.  Réducteur de pression haute température DNOVA PRA-S est équipé d'un refroidisseur d'impulsion (fourni avec le régulateur).  Le refroidisseur d'impulsion est installé entre le pipeline et la chambre à membrane, à laquelle le tube d'impulsion est connecté.  Avant la mise en service, le refroidisseur de régulateur est rempli d'eau du côté de la chambre à membrane.  L'installation d'un refroidisseur à impulsions est nécessaire pour empêcher que le liquide de refroidissement à haute température n'affecte la membrane.  La vanne de réglage est normalement ouverte lorsqu'il n'y a pas de signal (énergie).\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003eMatériaux et
