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 ...

Ball valves are widely used in oil and gas, chemical processing, energy and industrial pipeline systems where reliable shut-off is required. In these applications, the sealing system must maintain contact with the valve ball and sealing surfaces while handling the pressure of the working medium. This makes the pressure capability of a ball valve seal an important consideration when selecting a val...

Ball valve leakage does not always mean that the seal itself is defective. Sealing failure can result from material compatibility, pressure, temperature, installation, valve surface conditions or long-term wear.   Understanding the possible causes of failure is important when selecting or replacing ball valve seals, particularly in industrial pipeline and oil and gas applications.   What...
