Why use Südmo double seat valves? As well as a wide range, the series of these mixproof valves is characterized by ease of handling and maintenance, and is therefore the ideal component for operating your processes with maximum efficiency and safety.

  • Reliable separation of two media (e.g. product and cleaning liquid)
  • Two sealing elements work separately, leakage chamber open to atmosphere (avoids pressure build-up, visual leakage detection)
  • All surfaces in contact with product can be cleaned
  • Highest operating pressures (up to 10 bar / 145 psi)
  • Highest quality (body machined from a solid piece of bar)
  • EHEDG, 3-A, PMO, ATEX, CRN, FDA certifications

Simultaneous, programmed mixproof filling, emptying and cleaning of production lines without risk of contamination. Reliable separation of upper and lower valve housing allows one or more lines or tanks (purple and red lines) to be cleaned during production (yellow and green lines).
