Nearly maximum flow is achieved with minimal stem movement.<\/p>\n\n\n\n<p><strong>Applications:<\/strong><br>On-off valves are used in applications that require rapid access to high flow rates, such as on\/off control systems. They are not well-suited for precise control in intermediate positions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_Linear_Valve_Design_Linear_Characteristic\"><\/span><strong>2. Linear Valve Design (Linear Characteristic)<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><br><strong>Flow and Valve Position:<\/strong><br>In a linear valve, the flow increases in direct proportion to the valve position. For example, when the valve is 50% open, the flow rate is approximately 50% of the maximum flow.<\/p>\n\n\n\n<p><strong>Applications:<\/strong><br>Linear valves are preferred in situations where consistent and predictable flow control is required. They are used in pressure control systems or applications where precise flow adjustments are critical.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"3_Equal_Percentage_Valve_Proportional_Parabolic_Characteristic\"><\/span><strong>3.

When the valve is slightly open, flow changes are minimal, but as the valve opens further, the flow rate increases rapidly.<\/p>\n\n\n\n<p><strong>Applications:<\/strong><br>This type of valve is ideal for systems with wide operating ranges or pressure variations, where both low and high flow rates need to be carefully managed.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/unox.com.tr\/wp-content\/themes\/woodmart\/images\/lazy.svg\" data-src=\"https:\/\/unox.com.tr\/wp-content\/uploads\/2024\/11\/WhatsApp-Gorsel-2024-10-30-saat-13.06.16_7a6d0b7b-1024x1024.jpg\" alt=\"\" class=\"wp-image-62707\" title=\"\" srcset=\"\" data-srcset=\"https:\/\/unox.com.tr\/wp-content\/uploads\/2024\/11\/WhatsApp-Gorsel-2024-10-30-saat-13.06.16_7a6d0b7b-1024x1024.jpg 1024w, https:\/\/unox.com.tr\/wp-content\/uploads\/2024\/11\/WhatsApp-Gorsel-2024-10-30-saat-13.06.16_7a6d0b7b-300x300.jpg 300w, https:\/\/unox.com.tr\/wp-content\/uploads\/2024\/11\/WhatsApp-Gorsel-2024-10-30-saat-13.06.16_7a6d0b7b-150x150.jpg 150w, https:\/\/unox.com.tr\/wp-content\/uploads\/2024\/11\/WhatsApp-Gorsel-2024-10-30-saat-13.06.16_7a6d0b7b-600x600.jpg 600w, https:\/\/unox.com.tr\/wp-content\/uploads\/2024\/11\/WhatsApp-Gorsel-2024-10-30-saat-13.06.16_7a6d0b7b-768x768.jpg 768w, https:\/\/unox.com.tr\/wp-content\/uploads\/2024\/11\/WhatsApp-Gorsel-2024-10-30-saat-13.06.16_7a6d0b7b-1536x1536.jpg 1536w, https:\/\/unox.com.tr\/wp-content\/uploads\/2024\/11\/WhatsApp-Gorsel-2024-10-30-saat-13.06.16_7a6d0b7b.jpg 1600w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p><strong>Summary:<\/strong><\/p>\n\n\n\n<p><strong>Quick Opening:<\/strong> Ensures rapid flow increase for quick response, used in on\/off applications.<\/p>\n\n\n\n<p><strong>Linear:<\/strong> Provides proportional flow changes, suitable for applications requiring precise control.<\/p>\n\n\n\n<p><strong>Equal Percentage:<\/strong> Starts with slow flow changes but increases rapidly as the valve opens; ideal for variable conditions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Control valves regulate the flow of liquids or gases by adjusting the position of the internal mechanism (such as a<\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_joinchat":[],"footnotes":""},"categories":[434],"tags":[],"class_list":["post-62685","post","type-post","status-publish","format-standard","hentry","category-uncategorized-ru"],"_links":{"self":[{"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/posts\/62685","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/comments?post=62685"}],"version-history":[{"count":0,"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/posts\/62685\/revisions"}],"wp:attachment":[{"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/media?parent=62685"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/categories?post=62685"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/tags?post=62685"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
