SSC Check Valves

DN 40 – DN 600 | NPS 1½ˮ – 24ˮ

SSC check valves reliably prevent the backflow of corrosive and aggressive process media in piping systems. The PFA-lined design combines high chemical resistance with maintenance-free operation and is suitable for demanding applications in the chemical, pharmaceutical, and process industries.

Main Features

The SSC check valves were developed to reliably prevent backflow in piping systems carrying corrosive and aggressive media. Thanks to their robust, lined construction, they reliably protect plant components from unwanted backflow and contribute to safe and trouble-free operation.

The high-quality PFA lining ensures excellent resistance to chemically demanding media and protects all surfaces in contact with the media from corrosion. The smooth surface reduces deposits and supports high process reliability even in demanding applications.

Thanks to the freely oscillating disc, the check valves close reliably even at low system pressure. The maintenance-free design enables long-term, low-noise operation. The SSC check valves can be used in both horizontal and vertical piping systems and offer a reliable solution for applications in the chemical, pharmaceutical, and process industries.
