The flanged butterfly valve has a flange on the valve, and the two flanges on the valve are connected to the pipe flange with bolts. Flanged butterfly valves are not only widely used in general industries such as petroleum, gas, chemical, and water treatment, but also in the cooling water system of thermal power plants. The structural principle of the flanged butterfly valve is especially suitable for the manufacture of large-diameter valves.
When the flanged butterfly valve is in the fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body, so the pressure generated by the valve will be very small, and it is estimated that it has better flow control characteristics. The fluorine lined butterfly valve has two types of seals: elastic seal and metal seal. Elastic sealing valve, the sealing ring can be inlaid on the valve body or attached to the periphery of the disc. Valves with metal seals generally have a longer life than those with elastic seals, but it is difficult to achieve complete sealing. Metal seals can adapt to higher operating temperatures, while elastomeric seals have temperature-constrained defects.
Two-way sealing flanged butterfly valves are widely used in the current market. Many people choose it because its characteristics are very obvious. We can make better choices after understanding the specific use characteristics.
The small and lightweight flanged butterfly valve is very easy to use in the whole process, and it is also very easy to install, even if there is a fault, it can be disassembled in time. Enterprises choose such a butterfly valve because it can be installed in any position. We can also process and manufacture valves according to customer needs to ensure that they can be installed and used normally in many pipelines.
Simple structure is an important factor for many people to choose flanged butterfly valve wholesale. Of course, the butterfly valve itself is very compact and the torque during operation is very small. The 90-degree swivel opening is very convenient, and it is also very good in the whole adjustment process now, and it is not easy to leak in many aspects, especially the safety during use is also very high.
The reason why the seal of this flanged butterfly valve can be replaced is because it has a two-way seal, and the laminated plate can also be sprayed with coatings, such as nylon or PTFE, according to customer requirements during the purchase process. After a detailed understanding, we can choose according to the specific use function. In addition to effectively improving the overall sealing performance, it can also ensure a longer service life of the valve.
Simple and compact flanged butterfly valves from china valve factory are sold very well in the entire market. Consumers can also see the quotations given by different manufacturers during the purchase process. As long as they can ensure that the cost-effectiveness of the use is higher, they can be obtained in the market. Many people agree, and we can also see that the valve is very good in regulating performance, and there are no leak points.
