Tips: Brass ball valve sealing
The most important seat sealing ring material of the ball valve is polytetrafluoroethylene (PTFE), which is inert to almost all chemical substances, and has a small friction coefficient, stable performance, not easy to age, wide temperature range, and excellent sealing performance. Comprehensive characteristics. However, the physical properties of PTFE, including high coefficient of expansion, susceptibility to cold flow, and poor thermal conductivity, require that seat seal designs must be built around these properties. Plastic materials for seat seals also include filled PTFE, nylon, and many others. However, when the sealing material hardens, the reliability of the seal is compromised, especially under the condition of low-pressure drop. In addition, synthetic rubber such as nitrile rubber can also be used as a valve seat sealing material, but its applicable medium and temperature range are limited. In addition, if the medium is not lubricated, the use of synthetic rubber tends to jam the ball.
