Development of Butterfly Valve - 2013-06-21 15:09:52

What is a butterfly valve? The butterfly valve, which is generally favored by industrial manufactures of furnace, coal gas, natural gas, liquefied petroleum gas and many other engineering systems, is a valve that can be used for isolating or regulating flow.

The butterfly valve was invented by the United States in the thirties. At present, butterfly valves which are above general DN 300mm in size have gradually replaced the gate valve. The time of butterfly valve opening and closing is shorter than that of the gate valve. In addition, operation torque and installation space of the butterfly valve are smaller, and the weight of it is lighter. That's why most of manufacturers choose butterfly valve instead of a gate valve.

There are different kinds of butterfly valves. At the same time, soft seated butterfly valve and metal seated butterfly valve are playing an important role in the market of butterfly valve. We all know that each valve is adapted for different pressures and different usage. Specifically speaking, butterfly valves, seal gate valve and balance valve are used in the construction of many cities. Meanwhile, metal seated butterfly valve occupies an irreplaceable position in the heating system of the city; and the soft seated butterfly valve is the first to bear the brunt of the need for the environmental protection system of a city. Both soft seated butterfly valve and metal seated butterfly valve are used as piping systems which have been widely used in the petroleum, chemical, metallurgy, electricity and many other fields. The difference between them is the material of sealing surface. Of course, both of them have their own disadvantages, which need to pay more attention to the development of the butterfly valve industry.

It is mentioned that the High Performance Butterfly Valve are generally favored. But, it is why? There are several reasons for it. First of all, it can save money as it is lower in cost to other designs. What's more, it is lighter in weight, which means less support is required. With the development of the butterfly valve market, countless butterfly valve manufacturers tend to focus on the improvement of the quality of the butterfly valve.

Obviously, we can find that the butterfly valve occupies a large proportion in the mechanical products. It is reported that, according to the industrial countries, it accounted for about 5% of the value of the machinery industry. At the same time, as the important part of major technical equipment, the butterfly valve plays a key role especially in the power, petrochemical, metallurgy, city water supply and drainage system. With the development of technology, we believe that it will make an excellent process in its fields.
