The flanged PFA-lined check valve is a high-purity, corrosion-resistant unidirectional flow control device engineered for semiconductor wet processes, electronic chemical delivery, fine chemical and pharmaceutical piping systems. It enables automatic one-way flow and reliable backflow prevention with no external power required. The PFA lining delivers outstanding corrosion resistance and ultra-low ionic extractables.
Robust construction, one-way, low extractables, excellent corrosion resistance, and long service life. It is suitable for electronic-grade liquid delivery, fine chemicals, pharmaceutical engineering, new energy electrolyte pipelines and various corrosive medium control systems.
Danpore specializes in fluoropolymer fluid piping and lining engineering, serving CDS (chemical delivery system) chemical transport in semiconductor wafer fabs, and ultra-pure fluid piping systems for wet process applications. It is also used in display panel and photovoltaic wet process production lines.
