Les principaux arguments de vente de la vanne papillon \u00e0 plaquette (double excentricit\u00e9 + joint souple)
\nAvantages en mati\u00e8re de structure et d'installation
\nStructure \u00e0 double excentration\u00a0: l\u2019axe de la soupape pr\u00e9sente un double excentrage. Lorsque le papillon s\u2019ouvre d\u2019environ 20\u00b0, il se d\u00e9tache de son si\u00e8ge. Ceci r\u00e9duit consid\u00e9rablement les frottements, n\u00e9cessite un faible couple et assure une longue dur\u00e9e de vie.
\nRaccordement par bride\u00a0: sans bride int\u00e9gr\u00e9e. Structure compacte, poids l\u00e9ger, gain de place et installation rapide.
\nFacile \u00e0 installer, \u00e0 d\u00e9monter et \u00e0 r\u00e9parer : le si\u00e8ge de soupape peut \u00eatre remplac\u00e9 ind\u00e9pendamment sans d\u00e9monter le papillon ni la tige de soupape, ce qui r\u00e9duit les co\u00fbts d'entretien.
\nPoints forts en mati\u00e8re d'\u00e9tanch\u00e9it\u00e9 et de performance
\n\u00c9tanch\u00e9it\u00e9 bidirectionnelle parfaite\u00a0: joint souple (EPDM\/NBR\/PTFE) + si\u00e8ge \u00e0 l\u00e8vre\/flexible, joint \u00e0 bulles
\n\u00c9tanch\u00e9it\u00e9 dynamique\u00a0: plus le joint est \u00e9tanche, plus la pression est \u00e9lev\u00e9e. Elle compense les variations de temp\u00e9rature et de pression.
\nFaible r\u00e9sistance \u00e0 l'\u00e9coulement + Excellente r\u00e9gulation\u00a0: D\u00e9bit \u00e0 pourcentage quasi identique, double fonction de coupure et de r\u00e9gulation
\nAucun blocage \u00e0 l'ouverture et \u00e0 la fermeture\u00a0: faible friction, faible couple, convient aux applications manuelles\/turbin\u00e9es\/pneumatiques\/\u00e9lectriques
\nMat\u00e9riaux adapt\u00e9s aux conditions de travail
\nMat\u00e9riaux de haute qualit\u00e9\u00a0: Corps de vanne WCB\/304\/316\u00a0; papillon en acier inoxydable\u00a0; si\u00e8ge de vanne disponible en plusieurs mat\u00e9riaux \u00e9lastiques.
\nLarge champ d'application\u00a0: eau, huile, gaz, vapeur, milieux faiblement corrosifs\u00a0; -30\u00a0\u00b0C \u00e0 180\u00a0\u00b0C (selon les composants d'\u00e9tanch\u00e9it\u00e9)
\nHaute durabilit\u00e9 : peut supporter des dizaines de milliers de cycles d'ouverture et de fermeture sans aucune perte, convient aux conditions de commutation fr\u00e9quentes.
\nCo\u00fbt et rapport qualit\u00e9-prix
\nL\u00e9g\u00e8re et \u00e9conomique\u00a0: plus l\u00e9g\u00e8re que les vannes papillon \u00e0 brides classiques (mod\u00e8le 30%+), la vanne 30%+ r\u00e9duit la charge sur la canalisation et les co\u00fbts d\u2019installation.
\nLongue dur\u00e9e de vie + Maintenance facile : R\u00e9duit les temps d'arr\u00eat et la consommation de pi\u00e8ces de rechange, et pr\u00e9sente un faible co\u00fbt total sur l'ensemble du cycle de vie.<\/p>\n
