Fitur katup globe welding baja tempa / soket
1. Wis struktur kompak, katon ayu lan suda saluran aliran. Fitur struktural: BB utawa WB;
2. Lumahing sealing digawe saka baja paduan utawa karbida cemented. Matching saka bahan sealing cukup lan urip layanan dawa;
3. Cakram tutup iku kerucut, lan batang tutup diwenehake karo segel terbalik, kanthi kinerja sealing sing apik. Lumahing tutup tutup wis nitrided, kang nduweni resistance karat apik lan resistance gesekan. Kemasan nganggo grafit fleksibel, kanthi sealing sing dipercaya, operasi fleksibel lan torsi bukaan lan tutup cilik;
4. Macem-macem standar pipa lan wangun sambungan (kayata soket welding, butt welding lan sambungan Utas) bisa dipilih.
