Electric globe valve and flange gate valve belong to the same type of valve, consisting of electric actuator or pneumatic actuator and globe valve. The difference is that its closing part is a valve body, which rotates around the centerline of the valve body to achieve opening and closing. Gate valves are mainly used in pipelines to cut off, distribute, and change the flow direction of the medium. Two piece ball valve and three piece ball valve are a new type of valve widely used in recent years.
