Gemäss der vorliegenden Neuerung, welche beispielsweise -in der Abbil dtrag dargestellt ist, wird daher vorgeschlagen, einen verhältnismässig klein ausgebildeten Stahlring mit einer elastischen Au.Clage zu versehen, welche nicht nur auf der Druckseite zur Abdichtung der Stahlkugel angeordnet ist, sondern den Ver)ttlsltzring auch am Umfang umschliesst und dadurch zur Zentrierung des Ventilsitzes und zur Abdichtung der den Ventilsitz haltenden Flansche zwischen Saud- und Druck-ehäuse beiträgt. l";ei dieser in der Abbildung dargestellten Anordnung'aL,.c:ht die aus Stahl hergestellte Verit:i.lkugel (1) beim Schliessvor- gang zunächst ein Lz die kreisx'unde üffnu-_Z; der 11ppenfö,-,inir; ausgebildeten elastischen Auflage (7_.).

Damit der Stahlsitz (2) stets in der Mitte des Gehäuses (7) verbleibt und andererseits die als Dichtwulst (5) ausgebildete untere Hälfte der elastischen Ventilsitzaufläge mit der oberen Zippe (3) eine Einheit bildet, ist ein zylindrisches oder kegeliges Mittelstück (4) vorgesehen.So that the steel seat (2) always remains in the middle of the housing (7) and on the other hand the lower half of the elastic one, designed as a sealing bead (5) Valve seat supports that form a unit with the upper lip (3) are cylindrical or conical center piece (4) is provided.

Vorzugsweise wird beim Umgiessen des Stahlsitzringes (2) mit dem elastischen Material beim Herstellungsprozess eine feste Verbindung durch entsprechende Chemikalien angestrebt, so dass Stahlsitz und elastische Auflage eine untrennbare Einheit bilden.When casting around the steel seat ring (2) with the elastic Material in the manufacturing process is firmly bonded through appropriate chemicals aimed at, so that the steel seat and elastic support form an inseparable unit.
