<p>A valve particularly for vacuum drainage systems, comprising a valve housing (1) with an inlet (2), a through-flow part (11) and an outlet (3), and a device with an actuator for the opening and closing of the valve. The opening and closing device is a movable valve body (4) with a, relative to its axis, slightly inclined first sealing face stretching along the periphery of the valve body (4) up to a basically circular and, relative to the flow direction through the valve, vertical part comprising a second sealing face. The first sealing face is provided to rest against a corresponding inclined seat (16) being disposed on a projection in the valve housing and which seat is situated beyond the inner wall (36) of the through-flow part (11), and that the second sealing face is provided to be tightly resting against a corresponding circular, upper part (17) in the valve housing. <IMAGE></p> |
