1.The pipelines before and after the valve are ready, the pipelines should be coaxial, and the sealing surfaces of the two flanges of the flange connection valve should be parallel. The threaded connection valve thread should be intact. The thread standard should match the valve. The pipeline should be able to bear the weight of the valve, especially when the valve is installed lying flat, proper support should be made to the valve to prevent damage to the valve parts.

2.Purge the pipes before and after the valve to remove oil stains, welding slag and other debris in the pipes.

3.Check the mark of the valve to find out that the valve is intact. Fully open and close the valve several times to confirm that it is working properly

4.Remove the protective parts on the connecting ports at both ends of the valve.

5.Check whether there is any foreign matter in the flow passage in the valve. Even if there are only small foreign matter between the valve plate and the sealing surface, it may damage the sealing surface of the valve seat.
