Les vannes \u00e0 boule guid\u00e9e fonctionnent de la m\u00eame mani\u00e8re que les vannes \u00e0 boule flottante, mais dans ce cas, la boule est fix\u00e9e par un deuxi\u00e8me axe situ\u00e9 dans la partie inf\u00e9rieure du clapet, appel\u00e9 tourillon. Cela emp\u00eache la boule de bouger de son axe. Les vannes \u00e0 boule guid\u00e9e peuvent maintenir une \u00e9tanch\u00e9it\u00e9 ad\u00e9quate des deux c\u00f4t\u00e9s \u00e0 la fois. Cela est propice aux vannes \u00e0 3 ou 4 voies et aux vannes dans les applications \u00e0 tr\u00e8s basse pression o\u00f9 le d\u00e9bit n’est pas suffisant pour pousser la boule contre son si\u00e8ge en aval. <\/p>\n

Esta v\u00e1lvula de bola guiada es eficaz en aplicaciones de baja y alta presi\u00f3n, y requiere menos par de giro que las v\u00e1lvulas de bola flotante<\/a>.<\/strong><\/p>\n

Si\u00e8ge souple<\/h3>\n

Les vannes \u00e0 si\u00e8ge souple ont des surfaces d’\u00e9tanch\u00e9it\u00e9 en mat\u00e9riaux thermoplastiques non m\u00e9talliques tels que le PTFE, le nylon, le PEEK et autres… Elles fonctionnent \u00e0 des temp\u00e9ratures de service inf\u00e9rieures \u00e0 270 \u00b0C (en fonction du mat\u00e9riau d’\u00e9tanch\u00e9it\u00e9). Dans des conditions appropri\u00e9es, les vannes \u00e0 si\u00e8ge souple peuvent offrir un niveau d’\u00e9tanch\u00e9it\u00e9 tr\u00e8s \u00e9lev\u00e9 tout au long de leur dur\u00e9e de vie, g\u00e9n\u00e9ralement sup\u00e9rieur \u00e0 celui d’une vanne m\u00e9tallique classique.<\/strong><\/p>\n

Cependant, les vannes \u00e0 si\u00e8ge souple ne sont pas adapt\u00e9es aux milieux corrosifs, aux fluides de process sales ou abrasifs.<\/strong> Ces conditions peuvent endommager le si\u00e8ge souple et entra\u00eener des fuites. Elles ne peuvent pas supporter les m\u00eames pressions que les vannes \u00e0 si\u00e8ge m\u00e9tallique. Bien que les vannes \u00e0 si\u00e8ge souple soient souvent moins co\u00fbteuses que les vannes \u00e0 si\u00e8ge m\u00e9tallique, ces derni\u00e8res sont g\u00e9n\u00e9ralement plus adapt\u00e9es lorsqu’un service intensif est requis. <\/p>\n

D\u00e9couvrez-en davantage sur nos vannes \u00e0 boisseau sph\u00e9rique.<\/a><\/strong><\/p>\n
