Page 12: Assembly And Installation
The ball valves: - with flanged ends (TYPE 5220 & 5320), adapted for flanged connection with the pipeline ends that meet the valve flange dimensions per PN-EN 1092-1:2013 and PN-EN 1092-2:1999; - with welded ends (TYPE 5321), adapted for welded connection with the pipeline ends that meet the valve welded end dimensions per PN-EN 12627:2002. - Page 13 down, bolt the ball valve between the pipe end flanges. Add more gaskets if the flange to flange gap is too wide. Pressure test and strength test the pipeline with the valve fully open. Caution! If the product has mechanical damage, do not install it in the pipeline. The assembly method is shown in the following figure: OPERATION AND MAINTENANCE MANUAL 01-2016...
