Dixon Bellows Sealed Gate Valves: H8-Series, L-Series, and W8-Series.
When it comes to reducing fugitive emissions, bellows sealed valves are advantageous for a variety of applications. In refineries, where hydrocarbons and hazardous chemicals are processed, bellows sealed valves are used in steam, heating fluid lines, and volatile chemical services to prevent leaks. These valves are essential for ensuring emissions are contained. In the pharmaceutical and chemical industries, purity and safety are critical. Bellows sealed valves are used to prevent the contamination of products by atmospheric gasses or the release of toxic fumes. Bellows sealed valves are also utilized in nuclear and thermal power plants to prevent the leakage of radioactive gasses or steam. Cryogenic applications also benefit from the use of bellows sealed valves where gasses such as nitrogen, oxygen, and argon must be stored and transported at extremely low temperatures. These valves ensure there are no leaks, even under extreme temperature fluctuations.
Fugitive emissions are a silent but significant threat in industrial operations. Bellows sealed valves offer an
