Electric Butterfly Valve Installation Instructions

1. Before installation, it is necessary to carefully check whether the signs and certificates of the electric butterfly valve meet the requirements for use, and clean them after verification. Valves not installed and in use should be stored in a dry room. Valves that have been stored for a long time should be cleaned, dried, and coated with anti-rust oil regularly. Blind plates should be used at both ends of the valve to protect the flange sealing surface.

2. Install according to the flow direction of the medium; priority is given to horizontal installation.

3. The connecting bolts between the butterfly valve and the pipeline should be tightened multiple times in diagonal directions during installation, and should not be tightened at one time to prevent leakage at the flange joint caused by uneven force.

4. When installing the electric butterfly valve, it is advisable that the butterfly plate be in the closed position to prevent debris from entering the valve cavity and scratching the sealing surface.

5. When the valve is connected to the pipeline, it is required to use butt-welded steel flanges or special flanges for butterfly valves on the pipeline. If flat welded steel flanges are used, the inner hole of the flange must be as large as the inner hole of the gasket to ensure the effective sealing surface of the gasket.

6. The opening and closing strokes of the control mechanism have been adjusted when the electric butterfly valve leaves the factory. In order to prevent the wrong direction when the power is turned on, the user must manually go to the beginning of the 1/3 of the closing position before turning on the power for the first time. And check whether the direction of the indicator plate is consistent with the opening direction of the valve.

7. When the valve is in use, if any fault is found, stop using it immediately.
