摘要

The present invention relates to a sealing system particularly for industrial safety valves, more particularly for industrial ball valves. Thus, the present invention relates both to a sealing system and to a ball valve omprising said sealing system. The sealing system according to the present invention is of the type comprising an elastomeric element (500) and a thermoplastic element (600), and is characterized in that the elastomeric element (500) that provides fluid sealing is held in its seating exclusively by a thermoplastic element (600) and by the particular shape of the seating (400) of said elements within the seat (200), and is held stably in position by these.
