They are usually installed in a series of pipes. Isolation valves have different modes. When they are opened, the fluid can flow freely. By closing the isolation valve, the fluid stops flowing.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Isolation valves can also be categorized based on movement as well. They can be categorized into two different categories: <\/span><b>Rotary movement valves <\/b><span style=\"font-weight: 400;\">and <\/span><b>linear movement valves<\/b><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\">\n<h3><b>Rotary Movement Valves<\/b><\/h3>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">One of the popular <\/span><span style=\"font-weight: 400;\">types of isolation valves<\/span><span style=\"font-weight: 400;\"> is the rotary movement valve. Rotary movement valves have a rotational movement. They have two main designs: Ball valves and butterfly valves.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Ball valves contain a handle that shows its status. By checking the status you can ensure whether the valve is closed or open. These valves are great for a tight shutoff. One of the great advantages of ball valves is that they can be easily cleaned and their maintenance is not difficult as well. Since they can be easily cleaned, they have less potential for choke up. Because the sudden movement of the valve can damage the gauge or diaphragm of the transmitter, they should have a slow operation.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Needle valves, just like ball valves, are perfect for instrument isolation. Ball valves contain a hollow sphere with holes on each side. When the flow path aligns with the holes, there won\u2019t be any obstruction and the valve is in the open state. With the rotation of the ball, the valve will be closed and blocks the flow path of the fluid.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Butterfly valves contain a disc that rotates around a shaft. The disc\u2019s plane is parallel to the flow of the fluid when it\u2019s in the open state. This position is perpendicular when closed. These <\/span><span style=\"font-weight: 400;\">types of isolation valves<\/span><span style=\"font-weight: 400;\"> are great for low-pressure situations. Butterfly valves are compact as well. That is why they are great for places with limited space.\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\">\n<h3><b>Linear Movement Valves<\/b><\/h3>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">One of the different <\/span><span style=\"font-weight: 400;\">types of isolation valves<\/span><span style=\"font-weight: 400;\"> is the linear movement valve. These valves move in a straight line and that\u2019s why they are called linear movement valves. These valves have different designs such as gate valve, globe valve, diaphragm valve, and pinch valve.\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\">\n<h3><b>Diaphragm Isolation Valves<\/b><\/h3>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Membrane valves are also known as diaphragm isolation valves. These solenoid-operated devices utilize a diaphragm for sealing the valve seat. This enables the valve to isolate the flow path of the fluid. They can also work as a two-way or 3-way on and off system to work just for opening and closing the flow of the fluid.\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\">\n<h3><b>Rocker Style Isolation Valves<\/b><\/h3>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Rocker style isolation valves are just like diaphragm isolation valves and are solenoid-operated tools. These valves use a rocker system for rotation in order to seal the seat of the valve and stop the flow route of the fluid. These valves can be configured to work as a two-way system or as a multi-port diverter\/selector.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\">\n<h3><b>Pinch Isolation Valves<\/b><\/h3>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">A pinch isolation valve is also used for opening and closing the fluid\u2019s flow route. They have a disposable, removable tube that by pinching can open\/close the route.<\/span><\/p>\n<p><span style=\"font-weight: 400;\"><img decoding=\"async\" class=\"aligncenter size-full wp-image-13095\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/isolation-valve-1.jpg\" alt=\"Types of isolation valve\" width=\"1037\" height=\"734\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/isolation-valve-1.jpg 1037w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/isolation-valve-1-300x212.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/isolation-valve-1-1024x725.jpg 1024w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/isolation-valve-1-768x544.jpg 768w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/11\/isolation-valve-1-696x493.jpg 696w\" sizes=\"(max-width: 1037px) 100vw, 1037px\" \/><\/span><\/p>\n<p><em><strong>Read More on Linquip<\/strong><\/em><\/p>\n<ul>\n<li><span style=\"text-decoration: underline;\"><strong><span style=\"font-size: 10pt;\"><a title=\"Types of shut off valve: Your ultimate guide\" href=\"https:\/\/www.linquip.com\/blog\/types-of-shut-off-valve-your-ultimate-guide\/\" target=\"_blank\" rel=\"noopener\">Types of shut off valve: Your ultimate guide<\/a><\/span><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline;\"><strong><span style=\"font-size: 10pt;\"><a title=\"Types of plumbing valves: A complete guide\" href=\"https:\/\/www.linquip.com\/blog\/types-of-plumbing-valves-a-complete-guide\/\" target=\"_blank\" rel=\"noopener\">Types of plumbing valves: A complete guide<\/a><\/span><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline;\"><strong><a title=\"Types of Water Valves: The Ultimate Guide\" href=\"https:\/\/www.linquip.com\/blog\/types-of-water-valves-the-ultimate-guide\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-size: 10pt;\">Types of Water Valves: The Ultimate Guide<\/span><\/a><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline;\"><strong><span style=\"font-size: 10pt;\"><a title=\"A Comprehensive Guide To Different Types Of Air Valves\" href=\"https:\/\/www.linquip.com\/blog\/types-of-air-valves\/\" target=\"_blank\" rel=\"noopener\">A Comprehensive Guide To Different Types Of Air Valves<\/a><\/span><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline;\"><strong><span style=\"font-size: 10pt;\"><a title=\"Types Of Solenoid Valves: Everything You Need To Know\" href=\"https:\/\/www.linquip.com\/blog\/types-of-solenoid-valves\/\" target=\"_blank\" rel=\"noopener\">Types Of Solenoid Valves: Everything You Need To Know<\/a><\/span><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline;\"><strong><span style=\"font-size: 10pt;\"><a title=\"A Complete Tutorial To Learn About Different Types Of Check Valves\" href=\"https:\/\/www.linquip.com\/blog\/a-complete-tutorial-to-learn-about-different-types-of-check-valves\/\" target=\"_blank\" rel=\"noopener\">A Complete Tutorial To Learn About Different Types Of Check Valves<\/a><\/span><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline;\"><strong><span style=\"font-size: 10pt;\"><a title=\"Types of pressure relief Valve: All you need to know about PRVs\" href=\"https:\/\/www.linquip.com\/blog\/types-of-pressure-relief-valve-all-you-need-to-know-about-prvs\/\" target=\"_blank\" rel=\"noopener\">Types of pressure relief Valve: All you need to know about PRVs<\/a><\/span><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline;\"><strong><span style=\"font-size: 10pt;\"><a title=\"Types of non return valve: Introducing 6 types and more!\" href=\"https:\/\/www.linquip.com\/blog\/13040-2\/\" target=\"_blank\" rel=\"noopener\">Types of non return valve: Introducing 6 types and more!<\/a><\/span><\/strong><\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Why_do_we_use_different_types_of_isolation_valves\"><\/span><b>Why do we use different <\/b><b>types of isolation valves<\/b><b>?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Different isolation valves have been designed to stop the flow of different fluids. They can facilitate instrument removal for maintenance purposes. Using isolation valves can facilitate the stopping and diverting process media for different purposes such as changing the flow into another location. They are also capable of helping to shut down the process plants in the case of drain lines or vent lines. For maintenance or repair purposes, they are closed, but under normal circumstances, they remain open.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Advantages_and_Disadvantages_of_Different_Types_of_Isolation_Valve\"><\/span><b>Advantages and Disadvantages of Different <\/b><b>Types of Isolation Valve<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Now let\u2019s see the advantages and disadvantages of different isolation valve types.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Gate valve and piston valve contains advantages such as flow control, being able to work at high temperature, and well metal-to-metal sealing. Their disadvantages include only one-way flow (except for the gate valve), fluid accumulation may occur on the damper based on the type of the fluid resulting in the shortening of the stroke length.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Other types such as ball valves, butterfly valves, and monoblock valves have advantages such as minimum pressure drop, easy to use, perfect sealing, and remote position detection. They have a few disadvantages including heavy weight, and ruptures that may occur from the sealing element during the process. Another disadvantage is that opening and closing torque values after a certain nominal diameter are high because of their design.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">But keep in mind that while different <\/span><span style=\"font-weight: 400;\">types of isolation valves<\/span><span style=\"font-weight: 400;\"> have their own disadvantages, they have great advantages as well. Using them can ease up the flow control and help in maintenance purposes. So, you should decide which one offers more advantages and is suitable for your application.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">That was all there is to know about different <\/span><span style=\"font-weight: 400;\">types of isolation valves<\/span><span style=\"font-weight: 400;\">.
