The electric butterfly valve is divided into electric butterfly valve and non electric butterfly valve. The non electric butterfly valve can compensate axial, transverse and corner thrust, which simplifies the bearing design, corrosion resistance, high temperature resistance, sound elimination and other characteristics, and is especially suitable for hot air pipes and soot pipes. The feature of non electric butterfly valve is that the electric butterfly valve can compensate for multiple directions, which is much better than that of a single type of electric butterfly valve. When the electric butterfly valve is installed, the system error is inevitable. In the process of pipe connection, the optical fiber electric butterfly valve can better compensate the installation error. Moreover, the non electric butterfly valve is light, simple in structure, convenient in installation and maintenance, and relatively inexpensive.
In addition, the electric butterfly valve is used for absorbing pipes, pipes or vessels, and equipment with dimensional changes caused by thermal expansion and contraction, which is resistant to high temperature and pressure. The electric butterfly valve is so important to the pipeline, so how to select materials? Let's talk about how to select materials: according to the known conditions of the electric butterfly valve, such as working medium, service temperature, nominal pressure, connection mode, etc., and considering the forming and welding process of materials. The market source shall also be considered when selecting suitable materials.
