Double Expanding Gate Valve

Double Expanding Gate Valve adalah jenis katup (valve) yang dirancang khusus untuk mengatur aliran fluida dengan kemampuan yang unik untuk memperluas dua kali lipat saat dibuka. Katup ini menggunakan dua pintu gerbang yang dapat mengembang secara horizontal untuk membuka jalur aliran dan menyempit saat ditutup.

Double Expanding Gate Valve umumnya digunakan dalam industri minyak dan gas, petrokimia, dan industri lain yang memerlukan katup dengan pengontrolan aliran yang presisi, kemampuan penyegelan yang andal, serta kemampuan mengatasi tekanan dan suhu tinggi.
