Reducing fugitive emissions has become a high-priority goal for nearly all processing plants and facilities around the world. Often, the valve technology itself has a significant impact on fugitive emissions and therefore the life cycle cost of the equipment. According to the research, one of the largest sources of fugitive emissions in plants is associated with valves. The bulk of valve emission...

Valve stem packing seals are used in valves to provide a seal around the valve stem (the shaft that controls the valve's opening and closing). They are essential for preventing fluid or gas leakage from the valve, ensuring that pressure and contaminants don't escape. The application of stem packing seals includes: Pressure Control: They help maintain pressure within the valve, preventing leakage a...
