QOC Solutions produce chiusure rapide a ganasce. Le dimensioni consigliate per l’utilizzo di questa tipologia di QOC vanno da DN 6’’ a DN 72’’ con rating consigliato fino a ANSI 2500.

La QOC a ganasce è azionata attraverso l’avvitamento/svitamento di un tirante di manovra filettato che movimenta le ganasce permettendo il rilascio del coperchio per l’apertura.
