Double-seat Valves T-smart Mixproof Shut-off Valve 3000

T-smart double-seat valves enable reliable separation of dissimilar media in your production process.

The T-smart product label stands for

  • Standardized valve concept
  • Small and compact design
  • New standards with regard to ease of use and maintenance
  • Proven GEA quality and process reliability
  • High cost-effectiveness of production

The design - small and compact

T-smart seat valves are characterized by their extremely compact design. The resulting low weight enables easy handling especially for servicing work. Other advantages of this design only become obvious at “second glance”:

  • Balanced valve disks prevent undesirable water hammers, especially if the direction of flow is reversed (valve is closed in direction of flow), thus further improving process reliability.
  • Actuator systems kept short to minimize air consumption and reduce operating costs


  • The radial sealing system reduces cleaning effort to a minimum
  • The compact design minimizes the space requirement and ensures easy handling for maintenance work.
  • Double-balanced valve disk
  • The integrated lifting function makes a significant contribution to product safety during CIP/SIP cleaning.
  • Low number of product-contact seals


  • Design which enable gentle handling of the product
  • Conformity with all hygienic requirements
  • EHEDG certified
  • Full CIP/SIP capability
  • Unparalleled ease of maintenance
