Cleaning

Optimum cleaning is given if the seat lift actuator (E) drives
the valve seat into the position "on" during the cleaning process
(fig. 5.1).
During this process, the cleaning liquid can flush the seal
surfaces.
After termination of the cleaning step, the seat lift actuator is vented
and the valve seat moves into "closed" position by spring force.
7.1.
The flow chambers
The passages of the valve are cleaned by the cleaning liquid during
cleaning of the connected pipelines.
Depending on the degree and substances of soiling, cleaning
liquids, times and processes must be scheduled for the individual
application.
The compatibility of the individually selected cleaning processes
and liquids with the respective seal material must be verified.
