Lined valves used for strong corrosion conditions such as acid and alkali. The application areas are mainly in petroleum, chemical, paper, pharmaceutical, and electronics industry. To choose the cost-effective products, we should consult the data of pressure, temperature, price, friction, corrosion resistance, and flex life. The data below can make any help of the valve material decision.
Material | Temperature | Pressure | Price | Friction | Corrosion Resistance | Flex Life |
FEP | -30℃~150℃ | 150lbs | Medium | Medium | Good | Medium |
PTFE | -20℃~180℃ | 150lbs | High | Good | Good | High |
PFA | -30℃~200℃ | 150lbs | Medium | Good | Good | Medium |
Notice: Besides the above data, pressure and media is also to be considered. The lined valve are hardly accept granules scouring and high pressure.
