In jeder Ventilkammer (6, 7) ist gegenüber dem Ventilsitz (6a, 7a) ein Ventilteller (4a, 5a) angeordnet, der jeweils einstückig in eine Rollmembran (4, 5) integriert ist, die in der Ventilkammer (6, 7) mit ihren Rändern an der dem Ventilsitz (6a, 7a) gegenüberliegenden Seite (1a, 1b) des Ventilgehäuses (1) befestigt ist. Beide Ventilteller (4a, 5a) sind über eine in ihrer Bewegungsrichtung starre, mechanische Koppelungsvorrichtung (8) so miteinander verbunden, daß sich die Ventilteller (4a, 5a) in Bezug auf die Ventilsitze (6a, 7a) gegensinnig bewegen. Die Bewegung geschieht durch eine Betätigungsvorrichtung. Um eine Unabhängigkeit der Funktion vom Mediumsdruck zu erzielen, sind Membranen (4, 5) und Ventilteller (4a, 5a) so ausgebildet, daß die Wirkungsflächen der Membranen (4, 5) im wesentlichen gleich der Dichtflächen der Ventilsitze (6a, 7a) sind.
