Flanged Butterfly Valve is suitable for the transportation of various corrosive and non-corrosive fluid media in the engineering system of attacking furnace, liquefied petroleum gas, city gas, gas, natural gas, hot and cold air, chemical exercise and environmental protection, and construction of water supply and drainage. Used to condition and intercept media. Large-diameter flanged Butterfly Valve may have special requirements on the pipeline through the use of electric actuators or pneumatic actuators, electric flanged butterfly valves and pneumatic flange butterfly valves to achieve remote control.
Five elements of installing a flanged butterfly valve:
1. The butterfly plate of the flange butterfly valve is arranged in the diameter direction of the pipe.
2. The open orientation should be determined according to the rotation viewpoint of the disc.
3. When the disc is in the device, the disc should be stopped in a closed orientation.
4. Flange butterfly valve with bypass valve, open the bypass valve before opening.
5. The device shall be installed according to the instructions of the flange butterfly valve manufacturer. The heavy flange butterfly valve shall be provided with a solid root.
