What Is Fugitive Emission Valves?

Fugitive emission valves are specialized valves designed to minimize the escape of gases or liquids into the environment. These valves are crucial in industries where even small leaks can pose environmental and safety risks. They feature robust sealing mechanisms and undergo rigorous testing to ensure compliance with emission standards, such as ISO 15848 and API 622. Fugitive emission valves play a vital role in promoting environmental sustainability and maintaining safe operating conditions in industrial facilities.

How Does Fugitive Emission Valves?

Fugitive emission valves operate by utilizing advanced sealing mechanisms to minimize the escape of gases or liquids. These valves are designed with tight tolerances and durable materials to prevent leaks. During operation, the valve’s sealing components create a secure barrier, effectively containing the fluid or gas within the system. Through regular maintenance and adherence to strict testing standards, fugitive emission valves ensure minimal emissions, contributing to environmental protection and safety compliance in industrial settings.
