The sealing element is connected to a concertina element for sealing. The valve housing has a mainly spherical interior surface. The PTEF-lining is form-stable, and thick-walled, and pressed isostatically into the valve housing. The lining of the outlet socket diverges towards the flange end. Outer tubular ends of the lining are anchored in dove-tailed grooves in housing or flange surface.</p> |
