Cleaning and Packaging Low Fugitive Emissions

All integral-bonnet needle valves are cleaned and packaged in The American Petroleum Institute’s API 624 tests for fugitive
accordance with Swagelok Standard Cleaning and Packaging emissions to atmosphere for rising stem valves. The tests
(SC-10) catalog, MS-06-62. Cleaning and packaging in are conducted at a third party lab and certify that at no
accordance with Swagelok Special Cleaning and Packaging point in the test did the valve leak in excess of 100 ppm of
(SC-11) catalog, MS-06-63, to ensure compliance with product methane. Certificates stating that the valve is certified for
cleanliness requirements stated in ASTM G93 Level C are Low Emissions service are available for valves with PFA and
available as an option. PEEK packing. For more information, contact your authorized
Swagelok sales and service representative.
