Son profil compact le rend plus l\u00e9ger et plus court que les clapets anti-retour classiques.<br \/>\n Quels sont les principaux types de clapets anti-retour \u00e0 plaquettes ?<br \/>\n Les principaux types comprennent : le clapet anti-retour \u00e0 double plaque, le clapet anti-retour \u00e0 plaquette oscillante, le clapet anti-retour \u00e0 plaquette \u00e0 ressort et les clapets anti-retour silencieux sans \u00e0-coups.<br \/>\n Quelle est la diff\u00e9rence entre les clapets anti-retour de type wafer et de type \u00e0 oreilles ?<br \/>\n Les vannes \u00e0 plaquette sont fix\u00e9es entre les brides par des boulons traversants, tandis que les vannes \u00e0 oreilles sont dot\u00e9es de bossages filet\u00e9s qui permettent de les boulonner \u00e0 une seule bride pour une utilisation en bout de ligne.<br \/>\n Quelles sont les tailles et les pressions nominales disponibles ?<br \/>\n PANS propose des tailles de 2\u2033 \u00e0 36\u2033 (DN50\u2013DN900) et des classes de pression incluant 150LB, 300LB, 600LB et PN10 \u00e0 PN40.<br \/>\n Comment installe-t-on un clapet anti-retour de type plaquette ?<br \/>\n Il est fix\u00e9 entre deux brides correspondantes \u00e0 l'aide de boulons traversants. Assurez-vous que la fl\u00e8che indiquant le sens d'\u00e9coulement sur le corps est align\u00e9e avec le sens d'\u00e9coulement pr\u00e9vu.<br \/>\n PANS peut-il fournir des clapets anti-retour de type wafer personnalis\u00e9s\u00a0?<br \/>\n Oui, nous acceptons les commandes OEM avec des mat\u00e9riaux sp\u00e9ciaux (acier inoxydable duplex, Inconel), des pressions nominales personnalis\u00e9es et des dimensions face \u00e0 face non standard.<br \/>\n Quel est le prix des clapets anti-retour de type wafer de PANS\u00a0?<br \/>\n Le prix varie selon la taille et le mat\u00e9riau. En tant que fabricant, nous proposons des prix d'usine comp\u00e9titifs.
