Bellows Seal

Forged Steel Bellow Seal Gate Valves
 

A total containment solution is available with the installation of a 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.
