class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>As the name suggests, a floating ball valve uses a ball as the structure to close the cross-section of the pipe and prevent the flow of the fluid. Now, the main feature of a floating ball valve is that the ball has no structure to support it, so it stays suspended in the fluid and in place by valve seats.<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Flosting_Ball_Valve_Standards\"><\/span><span id=\"Flosting_Ball_Valve_Standards\"><strong>Flosting Ball Valve Standards<\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>a.

Obviously, the one-piece ball valve uses a sphere in which rotates around the center line of the body, while the flange gate valve opens a type of gate by lifting the blocking structure when the handle is rotated. The ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. Also known as integral ball valve, it is a new type of valve which has been widely used in recent years.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Two-piece_floating_ball_valve\"><\/span><span id=\"Two-piece_floating_ball_valve\"><strong>Two-piece floating ball valve<\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The two-piece floating ball valve takes its name from the fact that it is made of two parts called the left and the right body which are connected to each other through threads and bolts or by welding them.

The soft seal is the secondary seal, which is used to completely block the medium.<\/p>\n<p>\u2022 These seals are mainly used in applications where the working conditions include the presence of particles, dust, slurry and other media under normal temperature (below 150\u2103)<\/p>\n<p>\u2022 It has the advantages of having flexible operation, wear and erosion resistance, long service life and being a reliable sealing type.<\/p>\n<p>\u2022 The material used for soft seals (valve seat ring) is usually a type of rubber.<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-6161 aligncenter\" src=\"https:\/\/ntgdvalve.com\/wp-content\/uploads\/2024\/07\/03242208_00.jpg\" alt=\"\" width=\"600\" height=\"450\" srcset=\"https:\/\/ntgdvalve.com\/wp-content\/uploads\/2024\/07\/03242208_00.jpg 2560w, https:\/\/ntgdvalve.com\/wp-content\/uploads\/2024\/07\/03242208_00-768x576.jpg 768w, https:\/\/ntgdvalve.com\/wp-content\/uploads\/2024\/07\/03242208_00-1536x1152.jpg 1536w, https:\/\/ntgdvalve.com\/wp-content\/uploads\/2024\/07\/03242208_00-2048x1536.jpg 2048w, https:\/\/ntgdvalve.com\/wp-content\/uploads\/2024\/07\/03242208_00-600x450.jpg 600w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Floating_Ball_Valve_Pros_and_cons\"><\/span><span id=\"Floating_Ball_Valve_Pros_and_cons\"><strong>Floating Ball Valve Pros and cons<\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Ball_valve_advantages\"><\/span><span id=\"Ball_valve_advantages\"><strong>Ball valve advantages:<\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>\u2022 The fluid resistance is small, and the resistance coefficient is equal to that of the pipe section of the same length.<\/p>\n<p>\u2022 It has a simple structure, a small size and a light weight.<\/p>\n<p>\u2022 It is tight and reliable.

The main pipeline for oil and natural gas transportation needs to be a clean pipeline, and it needs to be buried underground. For buried pipelines, it is recommended to select full-diameter welded or flanged ball valves. For branch pipes, it is recommended to select flange connections or welded connections with a full diameter or a reduced diameter ball valve.<\/p>\n<p>b. For the pipeline and storage equipment of oil products, it is recommended to use flanged ball valves.<\/p>\n<p>c. For city gas and natural gas pipelines, the choice of suggested is floating ball valves with flange connection and female connections.<\/p>\n<p>d. The metallurgical oxygen piping system should use rigorously de-aliphatic oxygen valves.<\/p>\n<p>e. When working with fluids at very low temperatures, it is recommended to select the low temperature ball valve with a valve cover<\/p>\n<p>f. The pipeline system of the catalytic cracking unit of the oil refining unit can be used with a lifting rod ball valve.<\/p>\n<p>g. In the equipment and piping systems of corrosive media such as acids and alkali used in the chemical industry, it is appropriate to select stainless-steel ball valves made of austenitic stainless steel with polytetrafluoroethylene as the seat ring.<\/p>\n<p>h. Metal-to-metal sealed ball valves can be used on the piping systems or devices which work at high-temperature in metallurgical systems, power systems, petrochemical plants, and urban heating systems.<\/p>\n<p>i. When flow adjustment is required, worm gear drive, pneumatic or electric adjustment ball valve with V-shaped opening can be selected.<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-6164 aligncenter\" src=\"https:\/\/ntgdvalve.com\/wp-content\/uploads\/2024\/07\/03290925_07.jpg\" alt=\"\" width=\"600\" height=\"800\" srcset=\"https:\/\/ntgdvalve.com\/wp-content\/uploads\/2024\/07\/03290925_07.jpg 1920w, https:\/\/ntgdvalve.com\/wp-content\/uploads\/2024\/07\/03290925_07-768x1024.jpg 768w, https:\/\/ntgdvalve.com\/wp-content\/uploads\/2024\/07\/03290925_07-1152x1536.jpg 1152w, https:\/\/ntgdvalve.com\/wp-content\/uploads\/2024\/07\/03290925_07-1536x2048.jpg 1536w, https:\/\/ntgdvalve.com\/wp-content\/uploads\/2024\/07\/03290925_07-600x800.jpg 600w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Summary\"><\/span><span id=\"Summary\"><strong>Summary<\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>With many different types of valves in the market, it is important to understand the differences they have to be able to select the one that better matches the application in hand.<\/p>\n<p>Floating ball valves are a type of ball valve where the closing system stays suspended, which means it has a very simple design and operation, so it can be used for applications where the most important factors are the speed to open or close the flow, easiness to change the direction of such flow or simple installation.<\/p>\n<p>If more complex requirements are present, such as a higher resistance to harsh environments, high temperatures and high pressures, other designs should be considered. Perhaps using a two-piece or three-piece design would be a better idea, while considering the type of sealing is another important factor affecting the decision in those cases.<\/p>\n<p>By following the guidelines presented above, the selection should not be a major problem.
