we need to modify a piece of the pipe line to use it for pump minimal flow.

 

There is no much space on the line to add a orifice. The easiest location is at the valve flange.   

 

The valve is a DN80 ball valve. Will there be any risk or bad consequence ?

Hi,

 

Consider the link above . Refer to the documents attached with installation requirement , for minimum flow the distances may not be necessary , precision not required  .........  others will comment .

Hi,

 

I think your purpose is to kill the pressure and not measure flow on the minimum re-circulation line, hence you should not worry about the minimum upstream and downstream straight length requirement.
