1. A valve comprising: a valve axis extending in an axial direction; a valve housing comprising a first valve housing opening through which a flow medium can pass, the first valve housing opening comprising an edge; a seal, held on the valve housing by a ring and centered on the edge with respect to the valve axis; the ring surrounding the valve axis and secured to the first valve housing opening, the ring comprising: an annular base body axially engaged in the first valve housing opening; a first collar arranged to hold the seal on the valve housing; and a second collar axially engaged behind the edge; a spring for exerting a spring force; and a piston arranged in the valve housing, coaxial to the valve housing on the valve axis, and axially facing the first valve housing opening, wherein: the piston is axially movable in the valve housing against the spring force; and the first valve housing opening can be closed by the piston.
