Trunnion Ball Valve Multiple way – Multiport valves

Trunnion Ball Valve Multiple way – Multiport valves

Model no. VTL-VTT

Diverter and mixing valves ideal for flow switching and bypass operations with seals at every port, widely used in the Petrochemical and Refinery industries with highly viscous media or processes that have to continuously back flush their process lines.

Trunnion Ball Valve Multiple way - Multiport valves

GENERAL CONSTRUCTION
 

ERREESSE Multiport valves are engineered to switch critical processes and difficult media. They are often in 3, 4, 5 or 6 way construction with T, L or Y port, mostly used to split or combine process flows or to switch medium between alternative pieces of process equipment such as pumps, filters, strainers, meters, heat exchangers or complete pipelines, direct flow out of or into storage tanks, shutoff flow from different locations, in severe operating conditions with high flow rates, at high pressure and critical temperature conditions. Multiport valves can also be tandem or manifold mounted to further centralize control, also combined with smart positioners, jacketing, and automated control panels, suitable for electric, hydraulic or pneumatic actuation.
