In practical operation, the handle 51 is placed so that the segment plug 30 in the open position of the Valve comes in which a flowing medium can flow freely through the valve body 11, like the 3 Fig. 2 shows. jJie concave surface 32, with its concave inward has, cooperates with the side wall 11A in that a certain pre-selected height for the free Passage of a flowing medium through the valve body 11 arises.

If the valve is to be closed, then the handle 51 moved into the position shown in FIG. 3, in which the work surface 42 in contact with the valve seat 25 is coming. Once the working surface 42 has been rotated into engagement with the valve seat 25, the sealing ring 41 is sealed by means of the inclined surfaces 46, 47 which are compressed and by means of the deformed "O" ring 50. By the resilience inherent in the "O" ring 50 becomes the The work surface 42 is brought to bear against the valve seat 25.

Now a flowing medium can under excess pressure through the liquid passage 3b in the space 65 between the end of the pin 33 and the valve body 11 arrive. The flowing Medium will consequently press on the end of the pin 33 and counteract the force of the flowing medium; in order to there is a pressure on the concave surface 32 in the direction of the arrow 67
