The basic body has a first side () on which the seal support ring, in a mounted state on the valve housing, lies against the valve housing, and the seal support ring has a seal ring () made from an elastomer which, in its position on the basic body, surrounds the throughflow opening. A casing wall () is arranged on the basic body and at least partially surrounds the throughflow opening and, on a second side () of the basic body () opposite the first side, protrudes from the basic body and has a larger inside diameter than the seal ring.
