Katup bola adalah jenis katup seperempat putaran yang mengontrol aliran menggunakan bola berongga, berlubang, dan berputar di dalam badan katup. Ketika lubang bola sejajar dengan pipa, fluida mengalir bebas; ketika diputar 90 derajat, alirannya terblokir sepenuhnya. Mekanisme sederhana ini membuat katup bola sangat andal untuk aplikasi penghentian dan kontrol. Katup bola dikenal karena kinerja penyegelannya yang rapat, daya tahan, dan kemudahan pengoperasiannya. Katup ini dapat menangani kondisi tekanan dan suhu tinggi, dan cocok untuk media gas, cairan, atau bahkan korosif, tergantung pada bahan yang digunakan. Dengan penurunan tekanan minimal dan kontrol on-off yang cepat, katup bola banyak digunakan dalam industri seperti minyak dan gas, pengolahan air, pemrosesan kimia, dan perpipaan umum. Katup bola tersedia dalam berbagai jenis seperti dua arah, tiga arah, mengambang, dan terpasang trunnion, dan dapat dioperasikan secara manual, pneumatik, atau elektrik.
