Katup Gerbang Baja Tempa yang Dapat Menutup Sendiri
Katup gerbang baja tempa dengan sistem penyegelan otomatis dirancang untuk saluran pipa air, uap, dan minyak bertekanan tinggi serta bersuhu tinggi. Tutup katup (bonnet) dengan sistem penyegelan bertekanan ini meningkatkan keandalan penyegelan seiring meningkatnya tekanan internal. Katup ini tersedia dengan pilihan sambungan flensa berulir, RTJ, dan las ujung.
Deskripsi
Katup Gerbang Baja Tempa yang Dapat Menutup Sendiri
The self-sealing forged steel gate valve is designed for high-pressure and
high-temperature industrial pipeline service. Its pressure-seal bonnet design
uses internal pressure to improve the sealing force between the bonnet and the
valve body. As the pressure increases, the sealing performance becomes more
reliable.
The valve is suitable for water, steam and oil products. It is available with
forged carbon steel, alloy steel and stainless steel materials, as well as
flanged, RTJ and butt-welded connection options. The valve provides reliable
isolation with low flow resistance when fully open.
