When the valve handle is turned 90 degrees, the ball rotates, either aligning its bore with the flow path (open position) or placing the solid portion of the ball against the flow (closed position).<\/p>\n<p>The design is elegantly simple yet highly effective. The ball sits between two seats that create a seal when the valve is closed. This configuration provides excellent shutoff capabilities with minimal pressure drop when fully open, making ball valves ideal for applications requiring tight sealing and unrestricted flow.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Key_Components_of_a_Ball_Valve\"><\/span>Key Components of a Ball Valve<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"two-columns\">\n<div>\n<ul class=\"custom-list\">\n<li><strong>Ball:<\/strong>\u00a0The spherical core component with a bore (hole) through the center that controls flow<\/li>\n<li><strong>Valve Body:<\/strong>\u00a0The outer casing that contains the internal components and connects to the piping system<\/li>\n<li><strong>Stem:<\/strong>\u00a0The shaft that connects the ball to the external handle or actuator<\/li>\n<li><strong>Seats:<\/strong>\u00a0Typically made of PTFE or other materials, these create the seal between the ball and body<\/li>\n<\/ul>\n<\/div>\n<div>\n<ul class=\"custom-list\">\n<li><strong>Handle\/Actuator:<\/strong>\u00a0The external mechanism used to rotate the ball (manual or automated)<\/li>\n<li><strong>Body Seals:<\/strong>\u00a0Prevent external leakage from the valve body joints<\/li>\n<li><strong>Stem Packing:<\/strong>\u00a0Seals the stem to prevent leakage around the operating mechanism<\/li>\n<li><strong>End Connections:<\/strong>\u00a0Threaded, flanged, or welded fittings that connect to the piping system<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<h3><span class=\"ez-toc-section\" id=\"Working_Principle\"><\/span>Working Principle<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The operation of a ball valve is straightforward. When the handle is parallel to the pipe, the bore in the ball aligns with the flow path, allowing full flow. When the handle is perpendicular to the pipe, the solid portion of the ball blocks the flow path, stopping the flow completely. This visual indication of valve status (open or closed) is one of the many practical advantages of ball valves.<\/p>\n<p>The quarter-turn action makes ball valves quick to operate, while the tight sealing capability ensures minimal leakage when closed. The ball design also creates minimal resistance to flow when open, resulting in lower pressure drops compared to many other valve types.<\/p>\n<\/section>\n<section id=\"types-of-ball-valves\">\n<h2><span class=\"ez-toc-section\" id=\"Types_of_Ball_Valves\"><\/span>Types of Ball Valves<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-7138\" src=\"https:\/\/www.stvvalves.com\/wp-content\/uploads\/2024\/03\/c95800-2pc-ball-valve-800lb-dn25-npt-end-300x300.jpg\" alt=\"China C95800 2PC Ball Valve\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.stvvalves.com\/wp-content\/uploads\/2024\/03\/c95800-2pc-ball-valve-800lb-dn25-npt-end-300x300.jpg 300w, https:\/\/www.stvvalves.com\/wp-content\/uploads\/2024\/03\/c95800-2pc-ball-valve-800lb-dn25-npt-end-100x100.jpg 100w, https:\/\/www.stvvalves.com\/wp-content\/uploads\/2024\/03\/c95800-2pc-ball-valve-800lb-dn25-npt-end-600x600.jpg 600w, https:\/\/www.stvvalves.com\/wp-content\/uploads\/2024\/03\/c95800-2pc-ball-valve-800lb-dn25-npt-end-80x80.jpg 80w, https:\/\/www.stvvalves.com\/wp-content\/uploads\/2024\/03\/c95800-2pc-ball-valve-800lb-dn25-npt-end-768x768.jpg 768w, https:\/\/www.stvvalves.com\/wp-content\/uploads\/2024\/03\/c95800-2pc-ball-valve-800lb-dn25-npt-end-12x12.jpg 12w, https:\/\/www.stvvalves.com\/wp-content\/uploads\/2024\/03\/c95800-2pc-ball-valve-800lb-dn25-npt-end-36x36.jpg 36w, https:\/\/www.stvvalves.com\/wp-content\/uploads\/2024\/03\/c95800-2pc-ball-valve-800lb-dn25-npt-end-180x180.jpg 180w, https:\/\/www.stvvalves.com\/wp-content\/uploads\/2024\/03\/c95800-2pc-ball-valve-800lb-dn25-npt-end-705x705.jpg 705w, https:\/\/www.stvvalves.com\/wp-content\/uploads\/2024\/03\/c95800-2pc-ball-valve-800lb-dn25-npt-end-120x120.jpg 120w, https:\/\/www.stvvalves.com\/wp-content\/uploads\/2024\/03\/c95800-2pc-ball-valve-800lb-dn25-npt-end-450x450.jpg 450w, https:\/\/www.stvvalves.com\/wp-content\/uploads\/2024\/03\/c95800-2pc-ball-valve-800lb-dn25-npt-end.jpg 800w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>Ball valves come in various designs to suit different applications, pressure ratings, and control requirements.
