Stem Packing Set | Euroseal\u00ae Automatic"},"content":{"rendered":"<h2>Euroseal\u00ae Automatic Packing \u2013 Preformed Rings for Optimal Radial Expansion with Low Load<\/h2>\n<p>The Euroseal\u00ae Automatic configuration is a technical solution developed by General Packing as a valve stem sealing set.<\/p>\n<p>In its standard configuration, this packing set consists of 7 preformed rings: two top and bottom rings made of Euroseal\u00ae 2333 packing for anti-extrusion, three central sealing rings, and two adapter rings with differentiated shape and density.<\/p>\n<p>The conical design of the inner rings, combined with the use of Euroseal\u00ae graphite of varying densities, enables high radial expansion even with reduced tightening loads\u2014optimizing sealing performance without the need for mechanical preloading via springs.<\/p>\n<p>The result is a responsive packing set capable of dynamically adapting to operating conditions, delivering consistent performance over the long term.<\/p>\n<h3>Technical Advantages of installing and using the Euroseal\u00ae Automatic Valve Stem Packing Set<\/h3>\n<ul>\n<li>Automatic expansion: conical shape and differentiated density for progressive sealing activation.<\/li>\n<li>Reduced stem friction: up to 25% lower than square-section rings.<\/li>\n<li>Long service life without retightening: retains sealing properties even under thermal cycling and variable pressure.<\/li>\n<li>High dimensional adaptability: ensures effective sealing even on irregular seating surfaces.<\/li>\n<li>Compliance with regulations: developed to meet the most stringent standards for fugitive and environmental emissions.<\/li>\n<\/ul>\n<h3>Standard Configuration of the Valve Stem Packing Set<\/h3>\n<ul>\n<li>2 anti-extrusion rings (Top &amp; Bottom in Euroseal\u00ae 2333)<\/li>\n<li>2 high-density 30\u00b0 concave adapter rings<\/li>\n<li>3 low-density 45\u00b0 concave\/convex central rings<\/li>\n<\/ul>\n<p><img fetchpriority=\"high\"
