شیر توپی نوعی شیر یک چهارم چرخشی است که با استفاده از یک توپ توخالی، سوراخ دار و چرخان در داخل بدنه شیر، جریان را کنترل می کند. هنگامی که سوراخ توپ با خط لوله در یک راستا قرار می گیرد، سیال آزادانه جریان می یابد. با چرخش 90 درجه، جریان به طور کامل مسدود می شود. این مکانیزم ساده باعث می شود که شیرهای توپی برای کاربردهای خاموش و کنترل بسیار قابل اعتماد باشند. شیرهای توپی به دلیل عملکرد آب بندی محکم، دوام و سهولت کار خود شناخته شده اند. آنها می توانند شرایط فشار و دمای بالا را تحمل کنند و بسته به مواد مورد استفاده برای گاز، مایع یا حتی رسانه های خورنده مناسب هستند. با حداقل افت فشار و کنترل سریع روشن و خاموش، شیرهای توپی به طور گسترده در صنایعی مانند نفت و گاز، تصفیه آب، پردازش شیمیایی و لوله کشی عمومی استفاده می شوند. آنها در انواع مختلفی مانند دو طرفه، سه طرفه، شناور و نصب شده بر روی ران وجود دارند و می توانند به صورت دستی، پنوماتیک یا الکتریکی کار کنند.
