different industries, various devices are used to prevent damage to equipment. The structure of many devices that are placed in lines and in the flow path is such that they prevent the flow from returning and, if such an event occurs, it closes the fluid path. Next, we will examine how each of the industrial check valves works.  <\/p><h3>1. Flanged disc check valve<\/h3><p>One of the most widely used <strong>types of check valves<\/strong> is the disc-between-flange model. This type of check valve, due to its compact design, is very suitable for systems that are faced with space constraints. This type of check valve is very easy to install and it is also worth noting that it is light in weight. For this reason, this type of check valve is very popular among various industries.   <\/p><h3>2. Swing check valve<\/h3><p>Another &#8220;type of check valve&#8221; is the swing check valve, which reduces resistance to flow due to the free movement of the disc. This feature of the swing check valve allows the flow to pass through the system with minimal pressure. This is why the efficiency of the system is increased by using these check valves.  <\/p><h3>3. Ball check valve<\/h3><p>This type of check valve, known as a ball check valve, uses a ball or tube as the opening mechanism. For example, when fluid enters the valve, the ball moves up and the <span style=\"color: #334790;\"><a style=\"color: #334790;\" href=\"\/?product_cat=\u0634\u06cc\u0631-\u0633\u0648\u0632\u0646\u06cc-\u0628\u062e\u0627\u0631\" target=\"_blank\" rel=\"noopener\">steam needle valve<\/a><\/span> opens. Conversely, when pressure decreases, the ball moves down and the fluid flow is cut off.  <\/p><h3>4. Check valve lift<\/h3><p>In this type of check valve, a piston is used to open and close the <span style=\"color: #334790;\"><a href=\"\/?product_cat=\u0634\u06cc\u0631-\u062a\u0642\u0644\u06cc\u0644-\u0641\u0634\u0627\u0631\" target=\"_blank\" rel=\"noopener\">pressure reducing valve.<\/a><\/span> When the fluid flow goes under the piston and applies pressure to it, the piston in question rises and the valve opens. Also, as the pressure decreases, due to the weight of the piston and the force of gravity, the piston moves downward and the valve closes.<\/p><h3>5. Double check valve<\/h3><p><strong>The double check valve<\/strong> has a special design. In this type of industrial check valve, two axial plates are used. These two plates open and close symmetrically and prevent impact or damage to the system.  <\/p><h3>6. Poppet check valve<\/h3><p>Another name for <strong>poppet check valve<\/strong> is the silent check valve. These check valves have the ability to open and close very smoothly and do not make any impact. For this reason, they are noiseless and are called poppet check valves. This check valve is suitable for precise flow control due to its special internal parts.   <\/p><h3>7. Spring check valve<\/h3><p>Another type of <strong>industrial check valve<\/strong> is the spring-operated check valve. This type of valve has a disc that is attached to a spring. When the valve inlet exceeds a certain limit, the spring opens and pushes the disc upward.  <\/p><h3>8. Diaphragm check valve<\/h3><p>This type of <strong>industrial check valve<\/strong> has a flexible diaphragm that opens with fluid pressure and closes with pressure reduction or reverse flow. This type of check valve is suitable for corrosive fluids and suspended particles.  <\/p><h3>9. Angle check valve<\/h3><p>Angle check valve is another &#8220;type of industrial check valve&#8221; that has a specific application. One of <span style=\"color: #334790;\"><a style=\"color: #334790;\" href=\"https:\/\/www.tlv.com\/steam-info\/steam-theory\/other\/check-valve-installation-and-benefits\" target=\"_blank\" rel=\"noopener\">the advantages of installing<\/a><\/span> an angle check valve is its use in confined spaces with a specific angle. These check valves help reduce pressure and increase system efficiency.  <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-48f15d9d e-con-full e-flex wd-section-disabled e-con e-child\" data-id=\"48f15d9d\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-15cab71b elementor-widget elementor-widget-image\" data-id=\"15cab71b\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"693\" height=\"346\" src=\"https:\/\/etc-industrial.com\/wp-content\/uploads\/2025\/11\/image-2025-11-01T114657.837-1.png\" class=\"attachment-large size-large wp-image-5355\" alt=\"\u0628\u0631\u0631\u0633\u06cc \u0648 \u0646\u062d\u0648\u0647 \u0639\u0645\u0644\u06a9\u0631\u062f \u0686\u06a9 \u0648\u0644\u0648 \u0647\u0627\u06cc \u0635\u0646\u0639\u062a\u06cc\" srcset=\"https:\/\/etc-industrial.com\/wp-content\/uploads\/2025\/11\/image-2025-11-01T114657.837-1.png 693w, https:\/\/etc-industrial.com\/wp-content\/uploads\/2025\/11\/image-2025-11-01T114657.837-1-300x150.png 300w, https:\/\/etc-industrial.com\/wp-content\/uploads\/2025\/11\/image-2025-11-01T114657.837-1-150x75.png 150w\" sizes=\"(max-width: 693px) 100vw, 693px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-591930e3 e-con-full e-flex wd-section-disabled e-con e-child\" data-id=\"591930e3\" data-element_type=\"container\" id=\"3\">\n\t\t\t\t<div class=\"elementor-element elementor-element-7cb7e5d8 elementor-widget elementor-widget-heading\" data-id=\"7cb7e5d8\" data-element_type=\"widget\" id=\"33\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">What are the advantages of industrial check valves?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3d6cd10e color-scheme-inherit text-left elementor-widget elementor-widget-text-editor\" data-id=\"3d6cd10e\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>What is a <strong>check valve<\/strong>?
