A total containment solution is available with the installation of a Flowserve Vogt Bellowseal Gate Valve constructed to positively eliminate any leak paths at the bonnet joint and packing.
The valve, with its bellows and seal welded construction, totally confines the flow media within the valve pressure boundary. The valve packing is totally isolated by the bellows from the flowing medium and serves in a ”back up” role only.
