Fitur produk saka katup swing standar nasional
1. Prodhuk wis struktur cukup, sealing dipercaya, kinerja banget lan katon ayu;
2. Lumahing sealing dilapisi karo karbida semen adhedhasar Co, sing nduweni resistensi nyandhang sing apik, tahan korosi, tahan gores lan umur layanan sing dawa;
3. Dibangun ing struktur poros pin nyuda bocor njaba lan dipercaya digunakake;
4. Nalika meksa luwih saka utawa witjaksono kanggo 16.0mpa, struktur sealing self tightening diadopsi ing kamar tengah tutup. Sing luwih dhuwur tekanan medium, luwih apik kinerja sealing;
5. Materi lan ukuran flange lan mburi welding bokong bisa dipilih kanthi wajar miturut kahanan kerja nyata utawa syarat pangguna kanggo nyukupi macem-macem kabutuhan teknik.
