摘要：
The invention relates to a ball valve (1) for a pipe system for conveying liquid or gaseous media, comprising a housing (3), which has a ball plug (4) and seat rings (5, 6). A hydraulic system (7), which is independent of the pressure of the liquid or gaseous medium flowing through the pipe system, is provided for changing the contact pressure of at least one of the seat rings (5, 6) against the ball plug (4).
