Les vannes à pointeau Swagelok sont disponibles dans plusieurs configurations qui permettront aux utilisateurs de trouver des options adaptées à leurs besoins de performance et à la conception de leurs systèmes. Ces vannes à pointeau sont d’une grande fiabilité, que ce soit dans des applications basiques d’instrumentation à basse pression ou dans des applications à haute température et haute pression en milieu corrosif. Les vannes à pointeau Swagelok sont disponibles avec des coefficients de débit allant de 0,12 à 2,4. Elles sont également proposées avec une certification « faibles émissions » selon la norme API 624.
Également disponibles dans plusieurs configurations, les vannes de réglage fin Swagelok sont adaptées à une utilisation à basse et haute pression, et peuvent assurer un contrôle précis de l’écoulement dans des applications d’analyse, d’instrumentation ou de recherche. Avec des coefficients de débit allant de 0,004 à 0,16, elles permettent d’effectuer des réglages fins dans des applications qui requièrent un débit précis. Les différentes poignées disponibles pour les vannes de réglage fin permettent d’effectuer des réglages reproductibles du débit, de mieux contrôler les réglages ou de procéder au réglage en utilisant un tournevis dans des applications basse pression.
