Assembly Tips
During assembly, remove the plastic protective cover from the valve flap, clean it, tighten all matching components, and install the filter screen to avoid inhaling impurities.
The valve body and disc seals are precision ground, so when assembling, do not swap them up and down, let alone use them in tandem with other bottom valves, to avoid reducing the check performance. Once confused, it can be checked with ink coloring, which should coincide with the original grinding mark.
