In the world of industrial valves, fugitive emissions<\/strong> are not a minor detail<\/strong>. They are a technical requirement that impacts HSE<\/strong>, plant reliability, operational continuity and, increasingly, project specifications. This is why many requests for quotations explicitly include low-emission valves<\/strong> or design solutions aimed at reducing external leaks. <\/p>\n\n

For MTM Valves, this issue translates into a concrete approach: analysis of operating conditions, choice of materials, definition of packing and testing consistent with the project objective.1. Why fugitive emissions are an HSE issue and not just an environmental one<\/strong><\/p>\n\n

Fugitive emissions are unintentional releases of gases or vapours into the environment. In the field, they often do not present themselves as obvious leaks: they can be stable micro-leaks over time or phenomena that appear after thermal cycles, repeated manoeuvres, vibrations or mechanical adjustments. From an HSE perspective, there are two critical issues: potential exposure and difficulty in early detection. <\/p>\n\n

When the plant works with critical fluids (hazardous, aggressive, highly permeable or simply expensive), prevention also involves the correct selection of the valve and, above all, its seals.<\/p>\n\n

2. The key point: low emission packing<\/strong><\/p>\n\n

In most cases, the source of the problem is the valve stem seal<\/strong>. The packing must provide an effective barrier under real conditions: pressure, temperature, opening\/closing cycles, operating frequency and possible vibrations. <\/p>\n\n

When it comes to low emission valves, it is important to clarify a point that is often misunderstood: it is not enough to choose \u201ca good material\u201d. Low emission packing <\/em>only delivers the expected results if it is carefully designed, correctly installed and combined with a stem with suitable surface finishes and tolerances. <\/p>\n\n

3. Bellow seal valve: when it makes sense to use it<\/strong><\/p>\n\n

In some applications, the most effective solution for reducing external leakage is the bellow seal valve.<\/strong> The principle is simple: the bellows create a metal barrier between the process fluid and the stem area, drastically reducing the possibility of emissions through the traditional seal. <\/p>\n\n

That said, the bellows seal is not \u2018universal\u2019: it should be chosen when the operating profile, operating cycles and temperature\/pressure conditions make this design the most suitable. MTM Valves supports case-by-case evaluation, because the goal is not only to reduce emissions, but also to ensure the overall durability and reliability of the valve. <\/p>\n\n

Reducing emissions means designing the seal, not \u2018adding an option\u2019.<\/strong><\/p>\n\n

Fugitive emissions in valves<\/strong> are controlled through design choices and consistent checks: packing, stem, preloads, assembly and, where necessary, constructions such as bellow seal valves. MTM Valves works alongside customers and designers to define the most suitable solution for the service, using a method that integrates technical analysis and dedicated testing. <\/p>\n\n
