The Gate to Chemical Efficiency: How Gate Valve Suppliers Optimize Flow Control
Feb 18,2024Read More
The structural of flange butterfly valve is especially suitable for large diameter valves. Flange butterfly valve is not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of thermal power station. Commonly used ones are clip-on butterfly valve and flange butterfly valve. Clip-on butterfly valve connects the valve between two pipe flanges with stud bolts, while flanged butterfly valve has flanges on the valve and the two flanges on the valve are connected to the pipe flanges with bolts.
In the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure through the valve will be very small, and it is estimated that it has good flow control characteristics. Flange butterfly valves have two sealing types: elastic sealing and metal sealing. For elastic valve, sealing ring can be embedded in the valve body or attached to the periphery of butterfly plate. Generally, valves with metal seals have a longer service life than those with elastic seals, but it is difficult to achieve complete sealing. Metal seal can adapt to higher working temperature, while elastic seal has the defect of temperature constraint.
Pay attention to the direction when using stainless steel head, measure the outer circumference of the head, divide the measured outer circumference into four equal parts, and then mark the cylinder and the head.
Two-way flanged butterfly valve is widely used now, and many people choose it because its characteristics are very obvious such as flange valves for petrochemical. After knowing the specific characteristics, we can not only make a better choice, but also know the matters needing attention in the use process. Now there are many professional flange butterfly valve manufacturers in the market, and consumers can also choose flange butterfly valve manufacturers with high reputation. The structural features of flange butterfly valve are as follows:
The lightweight flange butterfly valve is very easy to use in the whole process, and it is also very easy in the installation process. Even if there is a fault, it can be disassembled in time. Enterprises will choose this butterfly valve because it can be installed at any position, and the valve can also be manufactured according to customers' needs, so as to ensure that it can be installed and used normally in many pipelines.
Simple structure is an important factor for many people to choose flanged butterfly valve. Of course, the butterfly valve itself is very compact, and the torque in the operation process is very small. The 90-degree rotary opening is very convenient, and now it is also very good in the whole mediation process. It is not easy to leak in many aspects, especially in the use process it is also very safe.
The reason why the seal of this flange butterfly valve can be replaced is that it has a two-way seal. In the process of purchasing, the laminated plate can also be coated according to the customer's requirements, such as nylon or polytetrafluoroethylene. After having a detailed understanding, we can choose it according to the specific function, which can not only effectively improve the overall sealing performance, but also ensure the longer service life of the valve.
Simple flanged butterfly valves sell very well in the market. Consumers can also look at the quotations given by different flanged butterfly valve manufacturers in the process of purchasing. As long as it is cost-effective, it can be recognized by many people in the market. And we can also see that the valve is very good in regulating performance and there is no leakage.
