Full-Lined PFA butterfly valves SB71-P PN10 DN50~DN350 were used for chemical plant in Moscow, Russia

Project Requirements:

The customer required wafer fluorine lined butterfly valves that would be suitable for high concentration hydrochloric, sulfuric, phosphoric acids.The medium’s working temperature is up to 150℃. The suppliers should recommend suitable lining material. Also, the customer required that the thickness of fluorine lining cannot be thin, because aggressive working medium will often grinds and corrodes the lining.

 Seallon`s Solutions:

● Considering that the working medium is a variety of acids with a concentration of 72-98%, Seallon recommend using PFA, which has the best corrosion resistance. In addition, the working temperature of the medium can reach up to 150 degrees, and PFA is most suitable because it can withstand up to 180 degrees.

● Seallon guarantees a 5mm thick PFA lining for all valve sizes. This robust lining ensures the longevity and durability of the valve, even in harsh, corrosive environments.

● Seallon’s wafer fluorine-lined butterfly valves feature a split body design, which allows for easy maintenance and replacement of critical components. Additionally, we offer spare discs and seats to extend the valve’s service life, ensuring reliable and continuous operation over time.
