Created with GIMP

Data has recently been presented that suggests that 80% of hazardous fugitive emissions come from ball valve stem leaks. To mitigate the threat of these emissions, several new technologies and devices have been designed.

One technology that has become more prevalent in the industry is media con­tainment devices. Media containment devices have been designed to deal with emission-specific problems by provid­ing a secondary sealing system that con­trols any leakage and allows the valve to continue in service until normal routine maintenance is scheduled.
