Membrane valves

are valves that use a membrane to control closing and opening. The product or the medium is only in contact with the membrane surface. All mechanical parts lie outside of the media-moistened area. GEMÜ Gebr. Müller Apparatebau has developed the first single-use membrane valve (GEMÜ SUMONDO). A polypropyl valve body that is welded to the membrane und connected with the impellent forms the single-use component. The valve body is discarded after its separation from the impellent.
