Katup globe adalah katup gerak linier yang utamanya digunakan untuk memulai, menghentikan, dan mengatur aliran fluida dalam pipa. Struktur internalnya mencakup elemen tipe cakram yang dapat digerakkan dan dudukan cincin stasioner dalam badan yang umumnya berbentuk bola—oleh karena itu disebut katup "globe". Ketika aktuator atau roda tangan diputar, batang menggerakkan sumbat ke atas atau ke bawah, mengubah jalur aliran dan menyediakan kontrol pelambatan. Desain ini menawarkan kemampuan mematikan yang baik dan sangat cocok untuk aplikasi yang membutuhkan pengaturan aliran yang presisi. Karena jalur aliran yang berliku-liku, katup globe cenderung memiliki penurunan tekanan yang lebih tinggi daripada jenis lainnya, tetapi dikompensasi dengan akurasi kontrol yang sangat baik. Katup globe sering digunakan dalam pemrosesan kimia, pembangkit listrik, dan sistem minyak dan gas di mana aliran terkontrol dan penyegelan yang rapat sangat penting. Katup globe dapat menangani berbagai fluida termasuk uap, air, minyak, dan gas, dan tersedia dalam versi aktuasi manual, pneumatik, atau elektrik. Fleksibilitas dan keandalan pengoperasiannya menjadikannya pilihan utama untuk sistem yang membutuhkan modulasi atau operasi yang sering.
