The installation of the butterfly valve should be taken carefully. Otherwise, the effects would be greatly influenced. As the variety of the prosperous butterfly valves, there would be different proper ways to install, such as trough the flanges. Now, let’s have a look at flanged single eccentric butterfly valve. It is a kind of valve which has taken good advantages of the flanged butterfly valve and the single eccentric butterfly valve so that the shortages of these two types of the butterfly valve have been effectively avoided.
The flanged single-eccentric butterfly valve is designed according to the streamline. It has effectively overcome the shortcomings of large friction resistance, hard disassembly and large loss of current. Therefore, it is widely used for cut-off and regulation in the systems of water supply, sewage treatment and neutral liquids in the mining industry, enterprises and high buildings. It is generally made up of the cast iron, ductile iron, carbon steel or the stainless steel. And the rubber seal help to ensure the good tightness.
Moreover, the flanged single eccentric butterfly valve holds other appreciated advantages, which are making great contributions to the popularity. The valve plate with the streamline truss structure can reduce fluid resistance. As the sealed valve seat is fixed on the valve plate, it isn't necessary to dismount the valve stem if you replace the sealed valve seat. And the used single-eccentric structure can reduce the abrasion of valve seat. Besides, the finish of heat-spraying epoxy resin monolithic coating can be suitable for the different medium, only after you replace the material of the sealed valve seat.
