TFM is a modified PTFE (polytetrafluoroethylene), commonly known as white polytetrafluoroethylene. This material has excellent chemical properties and is the lowest friction coefficient among all solid materials. The wide temperature range (-200 ℃ to+260 ℃) and mechanical properties makes it a widely used universal material. TFM Modified PTFE has the same excellent chemical resistance and thermal ...

A ball valve may look simple from the outside, but sealing becomes much more demanding when the valve operates under high pressure. The seal must maintain contact with the sealing surface while dealing with pressure changes, temperature variation, media compatibility, and repeated valve operation.   So, how does a high-pressure lip seal work in a ball valve, and what makes it different from a...

Ball valves used in oil and gas pipelines operate under demanding conditions. They may be exposed to high pressure, temperature changes, aggressive media, and repeated opening and closing cycles. In these applications, the sealing system plays an important role in maintaining valve performance and preventing unwanted leakage.   But what makes a ball valve seal suitable for API 6D applications...
