摘要： A compound aseptic double valve prevents doubly the passage of fluid between two ports spaced from each other. More particularly, the valve is highly aseptic and capable of providing a sealing and it is thus well suited for use in manufacturing and processing machinery or plants where food or beverage products are handled. The valve comprises a first valve member, a second auxiliary valve member mounted on a first valve shaft for actuating the first valve member, a second sleevelike valve shaft mounted on the first valve shaft to actuate the second auxiliary valve member on the first valve shaft, a second driving source provided independently of a driving source for actuating the first valve shaft and adapted to move the second auxiliary valve member and the second valve shaft on the first valve shaft in a direction which closes the valve, a valve seat for each of the first and second valve members to come into contact therewith, the valve seats being located in the same valve housing to provide a double sealing, and a bellows for sealing within the valve housing those portions of the first and second valve shafts which are moved in and out of the valve housing.
