| Structural Features | It is generally in the shape of a disc as a whole, with a circular through-hole in the center, which is used to install the valve stem and the disc of the butterfly valve. |
| Several bolt holes are evenly distributed along the edge of the disc. It is connected to the flanges of pipelines or other equipment through bolts to achieve sealing and fixation. | |
| There are two types: single flange and double flange. One side of the single flange has a connection structure, and the other side may have special designs such as flanging; the structures on both sides of the double flange are basically the same, which is suitable for different installation scenarios. | |
| Material Characteristics | Cast Iron: It has a relatively low cost, good wear resistance and compressive strength, and is suitable for some occasions where the requirements for corrosion resistance are not high and for transporting normal-temperature fluids, such as general water systems. |
| Cast Steel: It has high strength and good toughness, and can withstand relatively high pressure and temperature. It is often used in industrial pipeline systems, such as the transportation of steam and oil products. | |
| Stainless Steel: It has excellent corrosion resistance and oxidation resistance, and can be used to transport corrosive media, such as chemical raw materials, seawater, etc., and can also adapt to a certain high-temperature environment. | |
| Aluminum Alloy: It is lightweight and has good corrosion resistance. It is applied in some occasions where there are requirements for weight and the corrosiveness is not strong, such as the food and beverage industry, some air conditioning systems, etc | |
| Sealing Principle | The butterfly-shaped flange closely connects the two flange surfaces through bolts, and a sealing gasket is placed in the middle. When the bolts are tightened, pressure is generated on the flange surfaces, causing the sealing gasket to undergo elastic deformation and fill the tiny gaps between the flange surfaces, thereby preventing the leakage of the medium |
| Different sealing surface materials and structural designs can meet the requirements of different media and working conditions. For example, the rubber sealing surface is suitable for media such as water and air, and has good elasticity and sealing performance; the polytetrafluoroethylene sealing surface has a lower friction coefficient and a wider range of corrosion resistance, and is suitable for a variety of chemical media. | |
| Application Areas | Water Supply and Drainage System: It is used to control the on-off and flow rate of water flow, such as urban water supply pipelines, sewage treatment plant pipelines, etc. |
| Heating, Ventilation and Air Conditioning (HVAC) System: It regulates the air flow and controls the operation of the air conditioning system, such as the connection parts of air ducts. | |
| Industrial Pipeline System: In industries such as petroleum, chemical engineering, electric power, and metallurgy, it is used to transport various fluid media, such as steam, gas, oil products, acid and alkali solutions, etc., to achieve the opening and closing of the pipeline system and the regulation of the flow rate. |
