Classification and selection points of electric globe valve

Author:

The electric globe valve is relatively simple in structure and less classified. Generally, it is equipped with a 380V (also 220V or 660V) Z-type multi-turn electric actuator. It is used in the pipeline to cut off and cut off less frequently. If the switch is frequent, It is not suitable to choose this kind of valve. Because the unbalanced force encountered by the spool of the electric globe valve during switching is relatively large, when configuring the electric actuator, it needs to be appropriately larger. When the diameter is relatively large, an electric gate valve or other electric valve should be selected. instead.
Electric globe valves are commonly used electric straight-through globe valves, electric throttle valves, electric angle globe valves, electric DC globe valves, electric water seal globe valves, etc. Except for electric throttle valves, other electric globe valves are generally not used. High pressure option. If the electric globe valve is used in high pressure occasions, it is generally connected by butt welding, or an electric angle globe valve is used. According to the material, you can choose carbon steel or 304 stainless steel. If the temperature is relatively high, you need to choose chrome molybdenum steel or chrome molybdenum vanadium steel, which is typically the J941Y-170VP540 electric high temperature and high pressure globe valve used in power plants.
