Engineers must also evaluate how a valve influences flow resistance, energy consumption, and overall process efficiency. Among the many valve types used in piping systems, globe valves are widely recognized for their excellent throttling performance and precise flow regulation. However, they also generate a relatively high pressure drop compared to other valve designs.<\/p>\n<p class=\"isSelectedEnd\">Understanding the relationship between pressure drop and flow coefficient (Cv) is essential when selecting a globe valve for any application. An incorrect valve choice can lead to excessive energy loss, unstable control performance, increased operating costs, and premature equipment wear.<\/p>\n<p class=\"isSelectedEnd\">This article explores how globe valves create flow resistance, explains the importance of Cv values, and discusses why pressure drop matters in valve selection.<\/p>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h1><span class=\"ez-toc-section\" id=\"What_Is_a_Globe_Valve\"><\/span>What Is a Globe Valve?<span class=\"ez-toc-section-end\"><\/span><\/h1>\n<figure id=\"attachment_18670\" aria-describedby=\"caption-attachment-18670\" style=\"width: 300px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-18670\" src=\"https:\/\/oudianvalve.com\/wp-content\/uploads\/2026\/05\/CF8-Y-Type-Globe-Valve-5-Inch-Handwheel-PN64-RF-End-300x300.jpg\" alt=\"china CF8 Y Type Globe Valve,\" width=\"300\" height=\"300\" \/><figcaption id=\"caption-attachment-18670\" class=\"wp-caption-text\">CF8 Y Type Globe Valve<\/figcaption><\/figure>\n<p class=\"isSelectedEnd\">A globe valve is a linear motion valve designed primarily for regulating flow.
