Abstract: A system for maintaining the sterility of the environment inside a device used to transfer pharmaceutical, food or similar products from one container to another. A special flange for fixing the gasket has been created that is fixed magnetically to the body of the container; a diaphragm inside the gasket completely closes the shaft's through hole that controls the distribution device, with the subsequent division of the shaft into two semi-shafts that are connected via the diaphragm by magnets hidden in the surfaces of the two facing semi-shafts. The bottom part of the distributor container and the top part of the transfer container are closed by two plates of ferrous magnetic material that is fixed to the parts by magnetic fittings, which plates will be extracted after the two containers are connected. Finally, a cylindrical screen is lifted up before the valve is activated to transfer the product in order to prevent any connection between the inner part of the connected containers and the extractor.

Abstract: An improved butterfly valve for intercepting a conduit where substances flow, especially suitable for the pharmaceutical, alimentary and chemical fields The valve comprises an annular body (1) integral with the conduit and acting as a support for the rotation stem (4) of the butterfly valve dish (3), which is operable at one end by an actuating lever (6) to open or close the internal port of the annular body (1) where a sealing member (2), tightly engaging with the butterfly valve dish (3) in the closed position, is housed. The body (1) comprises means for allowing an extremely quick and easy mounting and dismounting operations for cleaning purposes without affecting the sealing ability, operability and minimum flow resistance when the valve is fully open. The sealing member (2) is shaped to require a low effort while closing the valve as well as assuring the seal even in correspondence of the stem (4) of the butterfly valve dish (3).
