If you want to do a good job in the maintenance of the pneumatic butterfly valve, you should pay attention to the overall cleaning work during the daily use. The cleaning work of any equipment is very critical when it is used. If some impurities enter it, it will directly affect the overall use of the equipment. Actively determine the actual problems in this area better, and do a good job of cleaning every period of time, which is the most basic for us.

Explanation on installation and maintenance of electric butterfly valve
1. When installing the valve, the valve chamber and sealing surface shall be cleaned in advance, and no dirt is allowed to attach to affect the sealing performance. During operation, clean the sealing surface and screw rod regularly and add lubricating oil.
2. Electric equipment, back handle and screw rod are not allowed to be used for lifting. Explanation on installation and maintenance of electric butterfly valve
3. The impurities in the pipeline to be installed shall be sorted (cleaned) together with the valve chamber to prevent the impurities from damaging the sealing surface and affecting the sealing performance.
4. During operation, the valve shall be operated by the control box or manual equipment, and other auxiliary tools are not allowed. Explanation on installation and maintenance of electric butterfly valve
5. When the valve is not used temporarily, it should be stored in the drying room. The diameter of the two ends is blocked. It is not allowed to stack the products arbitrarily to avoid damaging the relevant parts of the product.
6. Before the valve leaves the factory, the opening and closing positions of the travel of the electric device have been debugged. When the valve is installed on the pipeline and debugged, first switch to manual operation to open the butterfly valve plate about 30 degrees, and then restore the manual operation to electric operation. According to the instruction book, wiring diagram and control schematic diagram of the electric installation, after the correct wiring is confirmed, the valve can be opened and closed through the button on the control box. Remember that if the power line is connected reversely, the travel switch will fail and the worm gear, electric and electric butterfly valve will be damaged.
