Common troubleshooting methods for electric butterfly valves


1. Before installing the electric butterfly valve, it is necessary to confirm whether the performance of our factory's products and the flow direction arrow of the medium are consistent with the operating conditions. The valve chamber should be inserted and cleaned thoroughly. Impurities and foreign objects are not allowed to be attached to the sealing ring and butterfly plate. Before cleaning, the butterfly plate must not be closed to avoid damaging the sealing ring.


2. It is recommended to use a special flange for the disc plate installation of electric butterfly valves, namely HGJ54-91 socket welded steel flange.


3. The optimal position for installing an electric butterfly valve in a pipeline is vertical installation, but it cannot be inverted.


4. The use of electric butterfly valves requires flow regulation, which is controlled by a worm gear box.


5. For butterfly valves that have been opened and closed frequently, after about two months, open the worm gear box cover and check if the butter is correct. An appropriate amount of butter should be maintained.


6. Check that all connecting parts are required to be tightened to ensure the sealing of the packing and the flexibility of the valve stem rotation.


7. Metal sealed butterfly valves are not suitable for installation at the end of pipelines. If they must be installed at the end of pipelines, outlet flanges should be installed to prevent the sealing ring from accumulating or exceeding its position.


8. The installation and use of the valve stem should be regularly checked for valve effectiveness, and any faults should be promptly resolved
