    Principales caract\u00e9ristiques :<\/span><\/strong><\/h5>\n
      \n
    1. Garniture universelle :<\/span><\/strong> Tige et clapet en 13Cr avec si\u00e8ges rev\u00eatus d'alliage CoCr (garniture API 8), adapt\u00e9s jusqu'\u00e0 850 \u00b0F (454 \u00b0C). Les port\u00e9es sont rectifi\u00e9es et rod\u00e9es jusqu'au poli miroir pour une fermeture \u00e9tanche.<\/span><\/li>\n
    2. Tige non rotative :<\/span><\/strong> La tige non rotative \u00e9vite le grippage et s'adapte facilement \u00e0 la motorisation, avec un filetage Acme de pr\u00e9cision et une finition brunie.<\/span><\/li>\n
    3. Construction de pr\u00e9cision :<\/span><\/strong> Les pi\u00e8ces moul\u00e9es du corps et du chapeau sont usin\u00e9es avec pr\u00e9cision, avec un chapeau monobloc pour un meilleur alignement. Le presse-\u00e9toupe et le joint corps-chapeau sont usin\u00e9s avec un \u00e9tat de surface fin pour une \u00e9tanch\u00e9it\u00e9 totale et sans fuite.<\/span><\/li>\n
    4. Configurations polyvalentes :<\/span><\/strong> Disponible en corps droit, en Y et d'\u00e9querre, avec tige montante ou tige montante non rotative.<\/span><\/li>\n
    5. Aptitude \u00e0 la haute pression :<\/span><\/strong> Couvre les classes de pression de 150 \u00e0 2500, adapt\u00e9es \u00e0 l'isolement critique et au laminage.<\/span><\/li>\n<\/ol>\n
      Applications typiques :<\/span><\/strong><\/h5>\n
        \n
      1. Circuits d'eau de refroidissement n\u00e9cessitant une r\u00e9gulation du d\u00e9bit.<\/span><\/li>\n
      2. Circuits de carburant o\u00f9 la r\u00e9gulation et l'\u00e9tanch\u00e9it\u00e9 sont essentielles.<\/span><\/li>\n
