An electromagnetically actuatable 3/2-way valve for selectively connecting an output connection to a first or a second input connection is proposed, the connection being effected via a valve chamber to which the output connection is directly connected and to which the input connections are each connected via a sealing seat which can be shut off or opened by means of a movable valve closing member. The valve also has at least one electromagnet, the housing of which contains a magnet winding as well as a displaceable armature which, upon excitation of the electromagnet, actuates the valve closing member via a valve actuating plunger, a connection being made between the second input connection and the output connection when this valve closing member is in the inoperative position. In order to prevent a temporary lack of vacuum tightness during changeover (connection of all three connections), the invention provides that the valve closing member be formed by a flexible valve member (9) having a sealing face (27) which, when in the inoperative position, is prestressed in the direction of the first sealing seat (16) by means of a compression spring (21), the valve member (9) being provided during actuation with an intermediate position in which the two sealing seats (16, 17) are closed simultaneously. <IMAGE>
