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.
