4、 The electric ball valve has a wide range of applications. It is not only widely used in the petroleum, chemical and other industries, but also widely used in the cooling water system of thermal power plants. The electric ball valve must be hard enough to ensure that it can be used by industrial automation for a long time without deformation. The electric ball valve structure does not have any pipe joints in this type of valve body, and the electric ball valve will not be affected by the pipeline and other forces, so the whole structure shell will not be affected by the pressure, resulting in deformation or distortion of the valve body. 　　

2. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate stably and flexibly for a long time.
