Understanding these structural differences is crucial for selecting the appropriate valve for your application.<\/p>\n<div class=\"two-columns\">\n<div>\n<h3><span class=\"ez-toc-section\" id=\"Sealing_Mechanism\"><\/span>Sealing Mechanism<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The most significant structural difference is in the sealing system. Standard globe valves use compression packing (typically graphite or PTFE) that surrounds the stem and is compressed by a gland follower to create a seal. This design, while effective for many applications, can wear over time and may require periodic adjustment and replacement.<\/p>\n<p>In contrast, bellow seal globe valves utilize a metallic bellows that is welded to both the stem and bonnet. This creates a hermetic seal that completely isolates the process fluid from the environment, eliminating the potential leak path along the stem.<\/p>\n<\/div>\n<div>\n<h3><span class=\"ez-toc-section\" id=\"Stem_Design_and_Movement\"><\/span>Stem Design and Movement<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In standard globe valves, the stem moves directly through the packing, which creates friction and potential wear points. The stem is typically exposed to the process media, which can lead to corrosion or erosion depending on the fluid properties.<\/p>\n<p>Bellow seal globe valves feature a stem that is protected by the bellows assembly. As the valve operates, the bellows flexes (expands and contracts) while maintaining the seal integrity. This design protects the stem from direct contact with potentially corrosive process media.<\/p>\n<\/div>\n<\/div>\n<h3><span class=\"ez-toc-section\" id=\"Secondary_Sealing\"><\/span>Secondary Sealing<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Bellow seal globe valves typically incorporate a secondary packing seal as a backup safety feature. If the bellows should fail, this secondary seal prevents immediate leakage and provides time for maintenance.
