CA 2206953
A valve arrangement contains a housing (2) and a shut-off element (8) with which a shaft (10) is rotatably coupled, the passage of the shaft through the housing (2) being sealed by means of sealing elements (32). The valve arrangement is to be improved to the effect that, with little constructive expense, the leakage rate can be minimized and strict safety requirements can be satisfied, the valve arrangement being provided in its interior with a lining (20, 21). It is proposed that, as an option to the first sealing element (32), which is disposed in an annular space between the shaft (10) and the housing (2), a second sealing element (42) is disposed at least partially within a ring (3) joined to the housing (2). The lining (20) of the housing (2) reaches at least as far as the first sealing element (32) which is directly in contact with the lining (20), the first sealing element (32), and if necessary the second element, being compressible by means of a bushing (48) movable in the direction of the axis of rotation (14) of the shaft (10).
