electric globe valve

    Electric globe valve is a type of valve driven by electric actuators, widely used in industrial fields, especially in industries such as petroleum, chemical, pharmaceutical, fertilizer, and power. It is used to control the flow of media and achieve the purpose of cutting off or connecting pipeline media. The main advantages of electric globe valves are their easy operation, rapid opening and closing, convenient maintenance, and the ability to achieve remote control as needed, which improves work efficiency and safety.

Classification of electric globe valves

• Electric globe valves can be classified into various types based on their structure and application, including through type, DC type, right angle type, plunger type, etc. Each type has its specific application scenarios and advantages and disadvantages. For example, the straight through type has high fluid resistance and is suitable for situations that do not require frequent switching; Direct current and right angle types are more suitable for media containing solid particles or high viscosity due to their structural characteristics

Working principle of electric globe valve

• The working principle of an electric globe valve is to drive the valve disc to make linear or rotational motion through an electric actuator, so that the valve disc is tightly combined with the valve seat, achieving the effect of cutting off the flow of the medium. The closing principle of an electric globe valve relies on the electric thrust to rotate the valve stem, causing the sealing surface of the valve disc to tightly adhere to the sealing surface of the valve seat and preventing the flow of the medium

Compared with electric globe valve, other types of valves such as knife gate valve, ball valve, butterfly valve, etc. have different designs and applications. The layout of knife gate valves is relatively complex and suitable for working conditions that do not require frequent opening and closing, while ball valves and butterfly valves are suitable for regulating flow. The unique feature of an electric globe valve is that it has low friction between the sealing surfaces when it is closed, good wear resistance, and usually only one sealing surface, making it easy to manufacture and maintain.
