Valve for flowable media

A valve for flowable media, in particular for fluid adhesive or glue, comprising:

• a valve housing (21);
• a medium channel (20);
• a controllable actuator;
• a valve seat (22);
• a discharge opening (23) connected to the medium channel (20);
• a bellows (39) which is elongated in structure;
• a sealing element which is in the form of a hollow member and which is a part-piece of the bellows (39);
• a compensation means (44) which is in the form of an annular spacer piece (45);
• and
• a closure member (25) which is arranged in the valve housing (21) and which is elongated in structure,
• wherein the closure member (25) can be axially moved in the medium channel (20) of the valve by the controllable actuator and which in a closed position abuts the valve seat (22) and closes the discharge opening (23) and which is raised from the valve seat (22) in an open position and is released from the valve seat (22), and which is connected to the sealing element in order to seal the medium channel (20), the sealing element being movable in an axial direction during movements of the closure member (25),
• wherein another part-piece of the bellows (39) is fixedly supported in the valve,
• wherein the relative axial position between the bellows (39) and the valve seat (22) is adapted to a production-related deviation of the actual longitudinal dimension of the bellows (39) used from a desired longitudinal dimension, so that this deviation is completely or partially compensated for,
• wherein the compensation means (44) has a thickness that is selected to influence the relative axial position between the bellows (39) and the valve seat (22), in order to compensate for the deviation between the actual longitudinal dimension of the bellows (39) and a desired longitudinal dimension of the bellows (39),
• wherein the controllable actuator with which the closure member (25) is axially movable comprises an electromagnet (26) with a coil (28), the core or armature of which forms the closure member (25) or an armature portion (33) which is connected to the closure member (25), wherein the closure member (25) extends in the valve housing (21) from an end of the closure member (25) in abutment with the valve seat (22) in the closed position, through the medium channel (20) and through the space which is surrounded by the coil (28), as far as a region at the other side of the coil (28).
