Points to note for installation and maintenance of electric butterfly valves

1. Clean the valve cavity and sealing surface in advance when installing the electric butterfly valve. No dirt is allowed to adhere to affect the sealing performance. Regularly clean the sealing surface and the screw rod to add lubricating oil when in use.

2.The electric device, rear handle, and screw rod are not allowed to be used for lifting.

3. Clean up (cleaning) impurities in the pipeline to be installed while cleaning the valve cavity to prevent dirt and impurities from scratching the sealing surface and affecting the sealing performance.

4. The valve should be controlled by a control box or manual device during use, and no other auxiliary tools should be used.

5. When the valve is not used temporarily, it should be stored in a dry room, the diameter of the two ends is blocked, and the product is not allowed to be stacked arbitrarily to avoid damage to the relevant parts of the product.

6. Before the valve leaves the factory, the opening and closing positions of Denso's stroke have been debugged. When the valve is commissioned after the pipeline is installed, first switch to manual operation to open the valve plate of the butterfly valve by about 30 degrees, and then restore the manual operation to electric. According to the instructions, wiring diagrams, and control principle diagrams of Denso, after the correct wiring is confirmed to be correct, open and close the valves through the buttons on the control box. Remember that if the power cord is connected reversely, it will cause the travel switch to fail and damage the worm gear and electric and electric butterfly valves.
