Ultra low temperature ball valve

Kaitom low-temperature ball valves are mainly used in pipeline systems for flammable media (including natural gas) at room temperature. Kaitom low-temperature ball valves have the characteristics of flexible opening and closing, reliable sealing, fire resistance, and static electricity.
Product features of Kaitemu ultra-low temperature ball valve

Type: Floating and Fixed
Connection form: flange or butt welding
Nominal pressure: 2.0-10MPa
Nominal diameter: 20-400;
Minimum operating temperature: -196 ℃
