1. Before the device starts operation, use air spray to remove foreign objects on the piping, and clean the inner surface of the piping with clean water;
2. Carefully check whether the valve usage is consistent with its functional specifications;
3. Check whether there is any debris on the valve passage and sealing surface, and remove it in time;
4. The valve must be installed in time after unpacking, please do not loosen any fastening screws or nuts on the valve at will;
5. The wafer butterfly valve uses a dedicated butterfly valve flange;
6. The electric butterfly valve can be installed on the pipeline at any point of view. It is recommended not to invert the installation for the convenience of maintenance;
7. When installing the butterfly valve flange, ensure that the flange surface and the sealing rubber are aligned, the screws are evenly tightened, and the sealing surface is intact; if the screw tightening force is uneven, it will appear that the rubber bumps will jam the butterfly plate or resist the butterfly. The plate causes leakage at the valve stem.
