Cleaning the pipeline

We recommend additionally flushing the
pipeline with installed regulator before start-
up.
Î Unscrew the control line (18) from the
valve body.
Î Seal tight the valve body with stoppers
(see 'Accessories' in the Annex).
Î Observe the mesh size of the upstream
strainer for the maximum particle size.
Use strainers to suit the process medium.
Î Check the strainer for dirt each time the
pipeline is flushed and clean it, if neces-
sary.
If the regulator malfunctions due to clogging
after flushing the pipeline, proceed as de-
scribed in the 'Troubleshooting' section.
