Unique Operating Dynamics of Trunnion-Mounted Ball Valves

For a very long time, the idea has existed that a trunnion-mounted ball valve can be opened under full differential pressure if the piping system can withstand the rapid increase in pressure and the forces induced by it. As valve sizes and operating pressures increase, however, several factors need to be considered if that valve is opening with little or no pressure downstream. To learn more about the operating characteristics, factory testing, the study, transient analysis, and variables affecting performance, read the industry article on the Valve Magazine website.
