Single-seat Valves

ECOVENT® Shut-off valves

ECOVENT® single-seat valves are used for simple shut-off in hygienic applications. The valves are characterized by their ease of operation and flexibility.


In the simple shut-off, there is only one seal in the one piece valve disc separating the pipelines from one another. This means liquid can pass from one pipeline to the other in the eventuality of a seal defect. For this reason, single-seat shut-off valves are not suitable for separating incompatible products.

Special Features

  • Certified, hygienic configuration 
  • Metallic stop 
  • Flexibility because of the modular principle 
  • Proven seal geometry  

The ECOVENT® valve series is characterized by its compact design.
