Are Italian thin-walled ball valves suitable for high-vacuum environments?
Thread Content
Operating temperature: Ambient temperature; there may be steam flushing at 130°C (rarely). Operating pressure: -0.1 Mpa. Medium: Organic gases. Materials of the valve body, valve stem, and sealing surfaces: WCB/304/304/PTFE. Recently, I came across Italian-made thin-type ball valves. The manufacturer bragged a lot about them, claiming that they perform well under high vacuum conditions and even come with a 3-year warranty~~~~ Coincidentally, I currently have a project requiring many DN150 valves for use in a high-vacuum environment. I wonder how good their sealing performance is? I want to get in, but I’m afraid of running into problems
The feasibility of using Italian thin-walled ball valves in high-vacuum environments depends on their sealing performance as well as the temperature and pressure resistance of their materials. This valve uses PTFE as the sealing material; PTFE generally possesses good chemical stability and high temperature resistance, making it suitable for negative pressure environments of -0.1 Mpa. However, a high-vacuum environment places very high demands on sealing performance; it is recommended to ask the manufacturer for detailed experimental data and previous application cases to verify its performance under similar conditions. If possible, it’s best to conduct field tests to ensure it meets the project requirements. .
Floating ball valves are products designed for downstream sealing and are generally not used in vacuum environments; you can contact me at 13818500655
