I love to explain super typical words like, for example, fugitive emission. They are the typical words you hear on TV and read in magazines. Then you don’t even know what they mean. And that’s what I’m here for today. To explain in 5 minutes of nothingness what it means. So let’s go.
Fugitive emission valves or fugitive emission valves are a type of valve used in piping systems to attempt to eliminate the release of fugitive emissions. Fugitive emissions are uncontrolled leaks of gas or vapors from a system. I’ll leave it to you in inspirational quote mode:
Emisiones fugitivas: tipo de válvula que se utiliza en los sistemas de tuberías para intetnar la liberación de emisiones fugitivas.
I say it twice so that it sticks in our heads.
What are fugitive emissions in valves?
Fugitive emissions are small amounts of gases or liquids that escape from pipes, flanges, valves, tanks, and other equipment. These emissions include gases such as methane, steam, and carbon dioxide, as well as liquids such as oil or water. Fugitive emissions are a major environmental problem. AAAANDD can contribute to air pollution and climate change.
They not only have negative impacts on the environment but also on human health. They can cause respiratory and other health problems for those living near the source of emissions. In addition, fugitive emissions also include greenhouse gases such as methane. Methane is a major contributor to climate change. These emissions not only result in environmental degradation. They also result in the loss of valuable resources and financial losses for companies. In addition, there are also regulatory and legal compliance issues with fugitive emissions. Many countries have laws and regulations that limit the number of emissions that can be released into the atmosphere.
They can occur anywhere in the system but are most common at joints and connections.
Fugitive Emission design valves create a physical barrier between the inside of the valve and the outside atmosphere. This barrier is created by a seal usually located at the top of the valve. When the valve is closed, this seal prevents anything from escaping.
These valves are specially manufactured to pass various tests according to the most stringent standards. The aim: to ensure that they perform their function safely.
What Fugitive Emission Standards Exist?
It is necessary to differentiate between a production test and a typing test. A production test is performed on valves before they are installed. A type test is a test that is performed on a valve design to check its suitability. The type test validates the design but does not perform the test on the actual valve to be installed.
The most famous production tests are ISO 15848-2 or Shell SPE 77/312 or API 624 or TA Luft – VD 2440. In addition, the tests often require testing the valves several cycles and at different temperature intervals. Ta Luft is so famous that many fugitive emission valves are also called TA Luft valves.
A review of the different fugitive emissions standards
- API 624: This American Petroleum Institute (API) standard covers the design and testing of fugitive emission valves for use in the oil and gas industry. It establishes requirements for the leakage rate of valves, as well as for the materials used in their construction.
- API 622: This API standard is the first one to be done on the packaging before evaluating according to API 624. If it does not successfully pass API 622 we cannot continue with API 624.
- API 624: Specifies requirements for the design, materials, manufacture, assembly, testing, inspection, and documentation of fugitive emission valves. It requires about 310 cycles at different temperatures.
- ISO 15848: This international standard establishes requirements for the measurement of fugitive emissions from valves and other equipment in the oil and gas industry. It includes procedures for testing and reporting emissions, as well as guidelines for the design and manufacture of valves to minimize emissions.
- API 641: It is for valves that open and close with a quarter turn, for example, Ball valves.
- ISO 15848-1 (Type Test) and ISO 15848-2 (Production Test): Cover the measurement and evaluation of fugitive emissions from valves and other equipment in the oil and gas industry. Several cycles must be performed depending on the type of valve and give them a class based on the fugitive emission results. Class A: ≤ 1.0E-05 mg/(sm); ≤ 50 ppmv; Class B: ≤ 1.0E-04 mg/(sm); ≤ 100 ppmv and Class C: ≤ 1.0E-02 mg/(s*m); ≤ 500 ppmv.
- TA Luft: TA Luft stands for “Technical Instructions on Air Quality Control” and is a set of guidelines for air pollution control in Germany. It sets requirements for the measurement and reduction of fugitive emissions from valves. It includes various temperature cycles and valve cycles.
Other fugitive emission regulations
Environmental Protection Agency (EPA) VOC regulations in the United States of America: The EPA sets limits on the amount of volatile organic compounds (VOCs) that can be released into the atmosphere. These regulations apply to a wide range of industries. They include the oil and gas industry covering fugitive emissions from valves and other equipment.
The European Union (EU) Industrial Emissions Directive (IED) and the Industrial Emissions Regulation (IER) set limits on the number of fugitive emissions from valves and other equipment in the oil and gas industry within Europe.
Well, let’s move on from regulations that we have a few. If you have any more you can leave them in the comments.
Why is it important to avoid fugitive emissions?
There are several reasons why you should consider installing fugitive emissions-compliant valves:
- Environmental protection: Fugitive emissions can contribute to air pollution and climate change. By installing special valves that prevent fugitive emissions, you can help reduce the number of emissions released into the environment. You can help protect the health and welfare of people living near the source of emissions.
- Cost savings: Fugitive emissions can result in the loss of valuable resources, such as natural gas or oil, pressure, and steam. By installing anti-fugitive emission valves, you can help prevent these losses and save money.
- Safety: Fugitive emission valves are designed to prevent leakage and improve safety by providing guidelines for valve design and maintenance. So if the fluid is explosive or flammable they are your perfect candidate. You will avoid creating flammable vapors around the valves.
- Reputation: By installing valves that meet fugitive emissions standards, you can demonstrate your commitment to environmental responsibility. It can help enhance your company’s reputation.
Overall, installing fugitive emissions compliance valves can help you meet regulatory standards. Plus, you’ll protect the environment, save money and improve the safety of your operations. And don’t forget that you can enhance your company’s reputation.
Fugitive Emission Needle Valves
Needle valves are used to control the flow rate through a pipeline and are often part of the instrumentation lines of a system. They are also an important component in the control of fugitive emissions. Needle valves operate using a long stem that allows precise and tight control of the amount of flow allowed through the valve. They are ideal for instrumentation panels and high-pressure circuits.
At Redfluid we have special needle valves designed and tested to meet the requirements of standards such as API 624 or ISO 15848 and can be considered as needle valves to prevent fugitive emissions. These valves can be used in various applications such as the production, storage, and transportation of steam, gas, hydrogen, and oil as well as in other industries where the control of fugitive emissions is important. Learn more about Redfluid needle valves here.
Fugitive Emission Ball Valves
Fugitive emission ball valves work by blocking the flow of gas through a ball that is connected to a handle. Ball valves are easy to open and close. They can be used in both high and low-pressure applications. At Redfluid we have a wide range of valves designed and tested according to different fugitive emission standards.

Is there a Fugitive Emission, ATEX, and Fire Safe valve?
Although it may seem that the combination of these certifications in a single valve is very rare or impossible to find, a Fugitive Emission, ATEX, and Fire Safe valve do exist. And we say this with confidence because we have it. We have a needle, check, and ball valves that meet all three standards.
However, it is important for you to know that each certification is different from the others. The fact that a valve is Fugitive Emission does not mean that it is also ATEX. They are two very different things, although they are compatible. We share with you all the details about ATEX certification here.
The answer is yes. A valve can be designed to be both fugitive emission, ATEX and Fire Safe.
Fugitive emission valves are designed to minimize the number of gases or liquids escaping from pipelines or storage tanks. In addition, they meet regulatory standards such as API 624, ISO 15848, and others. Fire Safe is designed to prevent the release of hazardous materials in the event of a fire. ATEX valves are designed to comply with the European Union (EU) directive on equipment and protective systems for use in potentially explosive atmospheres.
At Redfluid we have valves that meet the requirements of these three categories. They incorporate features such as flame-retardant stem seals, which prevent the release of fluid in the event of a fire, tight tolerance ball or needle design, which helps minimize the amount of fluid leaking through the valve when closed, thus reducing the number of fugitive emissions, and ATEX certifications that ensure the valve is suitable for use in potentially explosive atmospheres.
