Beschreibung
Zusammenfassung:	FIELD: valving. ^ SUBSTANCE: seat comprises the ring with the ring groove that faces the surface of the spherical member to be sealed. The groove receives a part of the ring unit. The other part is made for permitting contact over the surface of the spherical member to be sealed. The unit has several ring bodies. The ring bodies are made of the first member made of, e.g., steel and the second sealing member made of, e.g., graphite. The second member is interposed between the bodies of the first member. From the side of inlet and outlet openings and spherical member the ring is provided with buffer members that provide resistance to the fluid flow. ^ EFFECT: improved operation capabilities. ^ 8 cl, 5 dwg
