New valve seal concept by Freudenberg

Freudenberg Sealing Technologies has recently developed a new cost-effective butterfly valve seal concept, that allows to produce butterfly valve seals made of EPDM, HNBR and Fluoroprene® XP from a common tool. Just one tool instead of three is required when butterfly valve seals made of several materials are in demand – which is often the case, like in pharmaceutical industries, since EPDM is better with there is contact with water, HNBR is better suited if there is risk of wear and Fluoroprene® XP is the best choice for contact with flavorings as well as polar, nonpolar and aggressive media.
