2. When installing a flanged check valve, it is necessary to use a flexible pipe on the segment that connects the valve with the butterfly valve. Avoid connecting the check valve directly with other valves to prevent unnecessary complications.

3. Within the operating range of the valve plate, necessary precautions should be taken, such as not introducing pipe joints or obstructions in this area, as it may lead to malfunction.
