Katup kupu-kupu adalah jenis katup seperempat putaran yang digunakan untuk mengatur, mengisolasi, atau memulai dan menghentikan aliran fluida dalam sistem perpipaan. Katup ini terdiri dari cakram atau pelat melingkar yang terpasang pada poros yang berputar. Ketika pegangan atau aktuator memutar poros 90 derajat, cakram bergerak dari posisi tertutup penuh ke posisi terbuka penuh, memungkinkan aliran melewati katup. Cakram tetap berada di jalur aliran meskipun terbuka, yang berarti selalu ada sedikit penurunan tekanan. Katup kupu-kupu dikenal karena desainnya yang ringkas, pengoperasian yang cepat, dan hemat biaya, terutama pada pipa berdiameter besar. Katup ini tersedia dalam berbagai jenis, seperti wafer, lug, dan gaya offset ganda atau rangkap tiga, tergantung pada tekanan dan persyaratan penyegelan. Katup ini banyak digunakan dalam industri seperti pengolahan air, HVAC, pengolahan kimia, minyak dan gas, serta makanan dan minuman, karena keandalannya, perawatan yang rendah, dan pemasangan yang mudah.
