Catalog sheet: 2.6-2.1
Disc closures consist of two (or more) metallic discs with a sealing rubber disc/ring between the metallic ones. Turning the handle the metallic discs gets closer to each other squeezing the sealing rubber disc/ring and pressing it against the interior wall of the pipeline. All disc closures are equipped with a ball bearing in order to reduce the force necessary to control the sealing element squeezing.
For the range of internal parameters of closed pipelines see the table
(other dimensions optional).
Metallic disc material:
Aluminium alloy as a standard, V4A steel upon request
