Abstract

A stop valve (1) comprises a housing (2) having a passage (15) for a reversible medium flow, which can be stopped by means of a valve body (20) having an annular portion of a sphere as a sealing surface (25), which includes a flat end portion (26). The transfer area between said sealing surface (25) and said flat end portion (26) is bent having a very small bending radius (r) and the bending radius (r1) of said sealing surface (25) is smaller than the maximum action radius (r2) of said valve body. Said valve body (20) cooperates with a sealing (36), which is annular and surrounds the passage and has an annular body (37), which via a constriction (38) is transformed into a seat ring (39). Said sealing (36) is, in the closing position of the valve, exposed with a smaller portion to that passage section, which houses said valve body, and with a larger portion to the other passage section. The mounting of said valve body allows a position adjustment in the direction of said seat but not in the direction away from the seat.
