Double-seat valves

For reliable separation of different media

Your benefits

  • Hygienic Design: A reduced number of sealings (3+2) and a product space designed to EHEDG meets highest hygiene requirements.
  • Simplicity: Thanks to the screw connection of upper and lower part of the double-seat valve, the valve seat position is twist-proof and thus be assembled reproducibly after sealing replacement. Leakage due to incorrect assembly can be ruled out.
  • Flexibility: The variable 360° connectivity paired with the multiple housing combinations allows any custom piping design.
  • Safety: The one-piece, massive valve housing with balancer is insensitive to pressure surges up to 45 bar.
  • Safety: The closed to the outside housing in combination with the flushing chambers prevent any contact of the product with the environment. On the inside of the double-seat valve, the self-draining valve housing with single-seat, leakage chamber and balancer cleaning allow hygienic, no-loss and safe production.
