CHISURA RAPIDA A DENTI

Le chiusure rapide a denti di QOC Solutions sono disponibili sia in versione manuale sia automatica. La QOC a denti si aziona attraverso un sistema di incastro a denti che ruotando ne consente l’apertura. La rotazione manuale è basata su un sistema a cremagliera; in caso di chiusura rapida automatica la rotazione si basa su un sistema composto da pistoni e pompa idraulici.

Per le QOC a denti consigliamo dimensioni comprese tra DN 6’’ e DN 46’’.

Il rating particolarmente consigliato è ANSI 150, ma la tipologia è applicabile fino a rating ANSI 600.
