SEAL ASSEMBLY

The invention relates to a seal assembly (100) for use in a fluid valve (10) which has a housing (20) and a flap (30) and which is designed to control a flow of fluid through a valve opening of the fluid valve (10) by adjusting the position of the flap (30) between a closed position and an open position. The seal assembly has a holding ring (110), which comprises a holding ring contact section (111) and a plurality of legs (112), and an annular flexible seal element (200), which has a circumferential radial web (201) and a first radial surface (202) that adjoins the radial web (201), is arranged on the upstream side when used as intended, and is designed to function as a centering surface in order to produce an interference fit together with a corresponding counter centering surface (23) of the inner wall (21) of the housing (20). A radial web (201) first lateral surface (203) which is arranged on the upstream side when used as intended is designed to rest against a contact surface (22) of the inner wall (21) of the housing (20), the holding ring contact section (111) has a holding ring contact surface which is designed to rest against a second radial web (201) lateral surface (204) which is arranged on the downstream side when used as intended, and free ends of at least one sub-quantity of the plurality of legs (112) are designed to be supported on a support section (24) of the inner wall of the housing (20) under pretension when used as intended, said support section extending substantially perpendicularly to the flow direction of the fluid.
