In the hygienic industry (milk, beer, yogurth, carbonated drinks, etc.) hygienic double seat valves are used for the distribution of materials to CIP filling lines, in addition to receiving products for diversion to storage tanks or compensation and separate between the cleaning medium and the product.

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)
  • Innovative sealing solutions (O-ring /RSC in seat area, form-fit profile seal in shaft area)
  • No mixing, no contamination between two medias
  • Optimized drive & control concept (ideal combination with Südmo IntelliTop 2.0 Control Top)
  • Easy to maintain (no special tools required)- low maintenance costs
  • 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 certification

 

How it works?

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 to be cleaned during production.

  • Area in contact with product: 1.4404 (AISI 316L)
  • Area not in contact with product: 1.4301 (AISI 304) / 1.4307 (AISI 304 L)
  • Control air pressure: Standard 6 bar (87 psi) – 8 bar (116 psi)
  • Operating Pressure: Standard 10 bar (145 psi)
  • Surfaces:
    • Product wetted: Ra < 0.8 um
    • Others: Ra 1.6 um
  • Seals: EPDM / HNBR / FKM
  • Connections acoording to:
    • DIN 11850-2 (DIN 11866-A)
    • ASTM A270 (DIN 11866-C) (ASME BPE-2009)
    • DIN EN ISO 1127 (DIN 11866-B)
