FIELD: machine building.
SUBSTANCE: sealing gasket for use with valve contains disk-shaped elastomeric ring and disk-shaped metal ring connected to shaped elastomeric ring to form sealing surface. Opening is made near the centre of the metal ring. Gasket holder is designed with cavity. Size of the holder and cavity is sufficient to receive elastomeric ring and metal ring. The other opening is made near the holder centre. Gasket stop is made with possibility to attach to the valve pin. Size of opening of the gasket holder and opening of the metal ring is sufficient to receive the gasket stop. The gasket stop may connect the gasket holder, elastomeric ring and metal ring with the valve pin thus providing connection of sealing with the valve seat by the metal ring. Fluid medium controller is described.
EFFECT: providing reliable sealing upon interaction with the valve seat.
