Certain custom configurations accommodate reverse flow, though shutoff performance often drops when operated counter to the recommended flow arrow.<\/p>\n<\/div>\n<\/div>\n<div class=\"faq-item\">\n<h3 class=\"faq-question\"><span class=\"ez-toc-section\" id=\"What_causes_the_non-clogging_capability_of_this_valve\"><\/span>What causes the non-clogging capability of this valve?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"faq-answer\">\n<p>The unobstructed flow path lacks the body cavities found in standard floating ball designs. The sharp edge of the V-notch segment continuously shears away deposits against the seat during rotation.<\/p>\n<\/div>\n<\/div>\n<div class=\"faq-item\">\n<h3 class=\"faq-question\"><span class=\"ez-toc-section\" id=\"How_does_a_segmented_ball_valve_compare_to_a_V-notch_globe_valve\"><\/span>How does a segmented ball valve compare to a V-notch globe valve?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"faq-answer\">\n<p>A segmented ball valve provides higher flow capacity and resists solid entrapment far better than a globe body. Globe valves generate higher pressure recovery losses due to their multi-turn, internal fluid turning passages.<\/p>\n<\/div>\n<\/div>\n<div class=\"faq-item\">\n<h3 class=\"faq-question\"><span class=\"ez-toc-section\" id=\"Which_actuators_operate_segmented_ball_valves\"><\/span>Which actuators operate segmented ball valves?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"faq-answer\">\n<p>Pneumatic rotary actuators, electric quarter-turn motors, and manual gear operators commonly actuate these assemblies. Actuator sizing must account for dynamic fluid breakout torque and mechanical seat friction.<\/p>\n<\/div>\n<\/div>\n<\/section>\n<section id=\"conclusion\">\n<h2><span class=\"ez-toc-section\" id=\"Choosing_the_Right_Control_Valve_Solution\"><\/span>Choosing the Right Control Valve Solution<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A segmented ball valve balances high flow capacity, continuous throttling control, and mechanical cutting ability within a compact rotary envelope.
