The invention relates to a double seat valve with a housing part in which there are two mutually adjacent valve seats and with two valve elements, which can be pressed alternately onto the two valve seats by a lever pivotable about a rocker bearing. The solution according to the invention essentially comprises a first bearing rib, which is arranged in the first housing part, between the valve seats, a second bearing rib, which is arranged on the lever, and an elastic second housing part, which connects the first housing part and the lever to one another in such a way that the bearing ribs are held in the correct position relative to one another. The second housing part also carries the valve elements. The purpose of the invention is to simplify a double seat valve to such an extent, in particular by virtue of the configuration of the rocker bearing and the arrangement of the valve elements, in such a way that the required overall volume is reduced and the effort involved in manufacture and the costs are reduced. The two bearing ribs of the rocker bearing roll on one another virtually without friction, with the result that only small actuating forces are required for the actuation of the double seat valve.
