They also comprise an axis around which the closing disk is pivotally mounted for pivotal movement about the longitudinal axis of the axis between the first and second positions.
  • Glatt ® type high containment valve sealing gaskets are also known for use in product transfer processes. Inflatable gaskets are currently used for such valves, which have the drawback that they deteriorate easily, so that, relatively frequently, traces of the gaskets fall onto the product being manufactured. Considering the known background, the download process currently follows the following basic sequence:
  • This system has the advantage that both valves are never in direct contact with the product, so the subsequent container transport process is a clean process, minimizing the risk of cross contamination that other systems do not avoid.

  • the anchorage systems known in the state of the art use adaptable infliable joints with the idea of mitigating this risk, since the joint itself when inflated produces a friction of the latter with the walls of the housing of the disc of the valve avoiding the accidental movement of opening or closing it, with which the locking system does not have a relevant function when used together with this type of inflatable joints.
