Low Emission Valves

Since the introduction of the U.S. Clean Air Act in 1963, the U.S.

Environmental Protection Agency (EPA) has set increasingly

stringent guidelines regarding fugitive emissions from industrial
facilities in general, and from valves in particular. Typically, valves

attribute 50% to 60% of methane emissions in a refinery plant, and

80% are associated with a valve stem leak.

Unlike valve body and flange static seals, the stem seal must function

properly in a dynamic environment. It has to endure cycle load, therm

al expansion, corrosive conditions, pressure fluctuation, and side loads.

Microfinish concentrated its R&D effort on low emission (Low ‘E’)

design performance of its floating and trunnion mounted ball valves.

The efforts resulted in a proven live loaded 'Cup and Cone' stem
packing which successfully passed the stringent requirements of

the ISO 15848-1 standard for fugitive emissions and also the API 641

standard requirements.
