In single-seat shuttle valves, there is only one seal for each switching position in the valve disc separating the particular pipelines from one another. Single-seat shut-off valves are not suitable for separating incompatible fluids.

Special Features
  • Certified, hygienic configuration
  • Metallic stop
  • Flexibility because of the modular principle
  • Proven seal geometry
  • Availability of two valve series


The ECOVENT® valve series is characterized by its compact design. Contrary to the VARIVENT® systems with multiple options, this series provides a simple and economical solution for standard requirements.


  • Single-seat divert valves
  • DN 10 – DN 100
  • OD 1" – OD 4"

Application Examples
In practice, these valves are frequently used in CIP supply and return lines. One typical application is also found at the end of a valve block in which the valves are fitted as divert valves between the process line and the drainage (e.g. during pushing out).

Recommended Flow Direction
To avoid water hammers when closing one path while the product is flowing, single-seat divert valves should be switched against the flow direction of the product if possible.
