Description du produit<\/h2>\n

Contrairement aux robinets \u00e0 tournant sph\u00e9rique qui se ferment en un quart de tour, les robinets \u00e0 tournant sph\u00e9rique se ferment en un quart de tour. Vanne \u00e0 guillotine<\/b> fonctionne en soulevant une porte rectangulaire hors de la trajectoire du fluide par l'interm\u00e9diaire d'un volant \u00e0 plusieurs tours. Lorsqu'elle est compl\u00e8tement ouverte, la porte lib\u00e8re compl\u00e8tement le passage, ne laissant aucune obstruction \u00e0 l'\u00e9coulement.<\/p>\n

Caract\u00e9ristiques techniques principales :<\/b><\/h2>\n
    \n
  • Mod\u00e8le :<\/b> GT<\/li>\n
  • Mat\u00e9riau du corps :<\/b> Acier inoxydable ASTM 316<\/li>\n
  • Pression nominale :<\/b> 200 WOG<\/li>\n
  • Gamme de tailles :<\/b> 1\/2\u2033 ~ 2\u2033<\/li>\n
  • Fonctionnement :<\/b> Volant (multi-tour)<\/li>\n<\/ul>\n

    Cette conception est particuli\u00e8rement utile dans les applications o\u00f9 le \u201ccoup de b\u00e9lier\u201d (ondes de choc provoqu\u00e9es par la fermeture soudaine de la vanne) est un probl\u00e8me, car le m\u00e9canisme de fermeture lente amortit naturellement les pics de pression.<\/p>\n

    Avantages et b\u00e9n\u00e9fices<\/h2>\n
      \n
    • Pr\u00e9vient les coups de b\u00e9lier :<\/b> Le fonctionnement multi-tour assure une r\u00e9duction progressive du d\u00e9bit, prot\u00e9geant les tuyaux et les pompes des chocs hydrauliques.<\/li>\n
    • Perte de charge minimale :<\/b> Lorsqu'elle est compl\u00e8tement ouverte, la vanne permet un \u00e9coulement direct avec une r\u00e9sistance presque nulle.<\/li>\n
    • Contr\u00f4le pr\u00e9cis :<\/b> Bien qu'il s'agisse principalement d'une vanne d'isolement, la tige filet\u00e9e permet un r\u00e9glage plus fin du d\u00e9bit qu'une vanne \u00e0 bille.<\/li>\n
    • Compact Face-to-Face :<\/b> G\u00e9n\u00e9ralement plus \u00e9troits que les robinets \u00e0 soupape, ils s'adaptent \u00e0 des espaces lin\u00e9aires plus \u00e9troits.<\/li>\n<\/ul>\n

      Domaines d'application et emplacements<\/h2>\n
        \n
      • Plomberie g\u00e9n\u00e9rale :<\/b> Vannes d'arr\u00eat d'eau principales pour les b\u00e2timents.<\/li>\n
      • Fluides visqueux :<\/b> Convient aux huiles plus lourdes pour lesquelles la r\u00e9sistance \u00e0 l'\u00e9coulement doit \u00eatre minimis\u00e9e.<\/li>\n
      • Alimentation en vapeur (basse pression) :<\/b> Isolation de base de la vapeur.<\/li>\n
      • Syst\u00e8mes d'irrigation :<\/b> Pr\u00e9venir les dommages caus\u00e9s aux canalisations par les coups de b\u00e9lier.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"

        R\u00e9gulation pr\u00e9cise du d\u00e9bit pour les syst\u00e8mes \u00e0 basse pression.<\/b><\/p>\n

        Le Vanne manuelle filet\u00e9e s\u00e9rie GT<\/b> est une solution classique pour la commande marche\/arr\u00eat lorsqu'un d\u00e9bit total avec une perte de charge minimale est n\u00e9cessaire.
