The electric characteristics and USES of stainless steel ball valve
Electric stainless steel ball valve just has to rotate 90 degrees of operating and small rotational torque can be closed tightly. Full equality of the valve body cavity for medium resistance is very small, straight flow channel. Electric stainless steel ball valve itself is the main characteristics of compact structure, easy operation and maintenance, and is applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be a whole, also can be combined. This valve shall generally be installed in the pipeline. Electric stainless steel ball valve is mainly used to cut or connect line in the medium, can also be used for flow regulation and control, it compared with other types of valve, has the following several advantages. 1, small fluid resistance, electric stainless steel ball valve is the smallest of all valve fluid resistance in the class a, even reducing ball valve, the fluid resistance is small. 2, thrust bearings reduce stem friction torque, can make the valve stem long smooth and flexible operation. 3, seat sealing performance is good, use the sealing ring made of elastic material, such as teflon structure is easy to be sealed, and electric stainless steel ball valve valve sealing ability increases as the medium pressure increases. 4, the valve stem seal is reliable, due to the valve stem will only be used as the rotation without lifting movement, the valve stem packing seal is not easy to damage, and sealing ability increases as the medium pressure increases. 5, such as ptfe material has good self-lubrication, with ball friction loss is small, so the electric stainless steel ball valve of long service life. 6, bottoms type valve stem and valve stem head convex order to prevent the valve stem, stem seal damage caused by such as fire, convex order between the body and also can form metal contact, to ensure that the valve stem seal. 7, anti-static function: in a sphere, the valve stem and valve body between spring, will be generated switching process of electrostatic export.
