It blocks the entire pipe bore and prevents fluid passage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A 90-degree rotation moves the disc parallel to the flow path. This creates an annular opening around the disc edge, allowing fluid through with minimal resistance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The aerodynamic disc profile reduces turbulence and pressure drop. Butterfly valves are more energy-efficient than gate or globe valves in large-diameter applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Butterfly valves support both on-off service and modulating (throttling) service. Flow characteristics depend on disc design and actuator type.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An equal percentage is the most common characteristic for chemical dosing and pressure control applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Linear types are preferred when more than 25% of the system pressure drop is available across the valve.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Quick-opening types are used for rapid isolation. These are rarely recommended for continuous modulation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Take note that butterfly valves are not full-bore. They are not compatible with pigging or swabbing operations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_are_the_Actuation_Methods_for_Chemical_Processing_Applications\"><\/span><strong>\u041a\u0430\u043a\u0438\u0435 \u0441\u0443\u0449\u0435\u0441\u0442\u0432\u0443\u044e\u0442 \u043c\u0435\u0442\u043e\u0434\u044b \u043f\u0440\u0438\u0432\u043e\u0434\u0430 \u0434\u043b\u044f \u0445\u0438\u043c\u0438\u0447\u0435\u0441\u043a\u043e\u0439 \u043f\u0440\u043e\u043c\u044b\u0448\u043b\u0435\u043d\u043d\u043e\u0441\u0442\u0438?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Selecting the right actuator directly affects process reliability and lifecycle cost.
