Welded ball valve

Multi-Valve offers a complete range of fully welded two or three-piece side-entry ball valves. The fully welded body construction provides a lighter solution while also avoiding potential leak paths to the external environment, ensuring reliable protection of the whole system. A solid double trunnion configuration and two independent seats with bidirectional sealing ensure the greatest level of tightness and reliability under high pressure and temperature conditions in all critical isolation services. Several unique features are available offering advanced technical solutions suitable for sweet or acid gas processes or pipelines applications. Material selection is fully customizable to meet customers project specifications.
