The electric ball valve is divided into electric ball valve and non electric ball valve. The non electric ball valve can compensate the axial and transverse direction, and there is no thrust at the corner, which simplifies the bearing design, corrosion resistance, high temperature resistance, noise elimination and other characteristics, and is especially suitable for hot air pipes and soot pipes. The feature of non electric ball valve is that the electric ball valve can compensate for multiple directions, which is much better than the electric ball valve that can only compensate for a single type. When the electric ball valve is installed, the system error is inevitable. In the process of pipe connection, the optical fiber electric ball valve can better compensate the installation error. Moreover, the non electric ball valve is light, simple in structure, convenient in installation and maintenance, and relatively inexpensive.
In addition, the electric ball valve is used to absorb the pipe, pipe or vessel, and the equipment with dimensional changes caused by thermal expansion and contraction, which is resistant to high temperature and pressure. The electric ball 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 such as the working medium, service temperature, nominal pressure, connection mode, etc. of the electric ball valve, and considering the forming and welding process of materials. The market source shall also be considered when selecting suitable materials.
