    Un actionneur pneumatique à demi-tour de type Scotch-Yoke
    est un mécanisme industriel robuste qui convertit le mouvement linéaire d'un piston en un mouvement rotatif de 90° pour ouvrir/fermer des vannes, offrant un couple maximal au début et à la fin de la course, idéal pour les vannes à bille ou à papillon .

    Caractéristiques principales et avantages :
    • Couple élevé : Particulièrement adapté aux applications exigeant une forte force de décollage et de fermeture, le couple étant le plus élevé en début et fin de mouvement.
    • Types : Disponible en versions double effet (DA) et simple effet (SR - avec retour par ressort).
    • Fonctionnement : La pression de l'air agit sur un piston, entraînant une tige coulissant dans une fente (yoke), ce qui fait tourner l'axe de la vanne.
    • Construction : Conception robuste, souvent avec des corps en fonte ductile ou acier au carbone, et des composants internes protégés (nickelés) pour une longue durée de vie.
    • Performance : Conçu pour des pressions d'air de 3 à 7 bars, avec des couples atteignant des centaines de milliers de Nm.
    • Sécurité et conformité : Conforme aux normes ISO 5211 et NAMUR, avec des options pour les environnements dangereux (ATEX, SIL 3).
    Ces actionneurs sont largement utilisés dans les applications de sécurité (ESD) et de contrôle, grâce à leur fiabilité dans les environnements difficiles.
