1. Before installation, it should be confirmed whether the product performance and the flow direction arrow of the medium are consistent with the moving conditions, and the inner cavity of the valve should be cleaned. It is not allowed to have impurities attached to the sealing ring and disc, and it is not allowed to close before cleaning. disc, so as not to damage the sealing ring.
2. It is recommended to use special flanges for butterfly valves for the installation flanges of pneumatic butterfly valves.
3. The position where the pneumatic butterfly valve is installed in the pipeline, the good position is vertical installation, but it cannot be installed upside down.
4. The flow rate needs to be adjusted in the use of pneumatic butterfly valves, which are controlled by pneumatic actuators.
5. For the manual butterfly valve with many times of opening and closing, in about two months, open the cover of the worm gear box to check whether the butter is normal, and keep an appropriate amount of butter.
6. Check that the connection parts are required to be pressed tightly, which not only ensures the sealing of the packing, but also ensures the flexible rotation of the valve stem.
7. The metal-sealed pneumatic butterfly valve is not suitable for installation at the end of the pipeline. If it must be installed at the end of the pipeline, it is necessary to install the outlet flange to prevent the sealing ring from overstocking and over-positioning.
8. Valve stem installation and use response Regularly check the valve's use effect, and find faults and eliminate them in time.
