[Check valve Features]
 

 

  • Excellent in sanitary purpose
    There are no foreign material generation because no sliding and rotating section which may become the source of particle generation in the flow path. There is no dead space for liquid and no remaining fluid.

  • Small foot print, simple structure
    Small feature size and small installation space. Simple structure and excel in maintenance.

  • No restriction on fixing direction.
    Correct operation is performed by fixing both horizontal and vertical directions. Connection complies with the sanitary specification.

  • All parts are made of SUS316L
    Sealing section excels in durability and heat resistance and secures stable sealing characteristics because all of them are made of metal. Parts are machined from the raw material which does not have caving and pinhole inside a casting.
