Electric globe valve and flange gate valve are the same type of valve, composed of electric actuator or pneumatic actuator and globe valve two parts, the difference is that its closing part is a valve body, the valve body rotates around the center line of the valve body to achieve the opening and closing of a valve. Gate valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Two-piece ball valve, three-piece ball valve, is a new type of valve widely used in recent years.

advantage

1. Simple structure, convenient manufacturing and maintenance.

2, small working trip, short opening and closing time.

3, good sealing, small friction between the sealing surface, long life.

4. The structure of the globe valve body is straight-through, straight-flow and right-angle. Straight-through type is the most common structure, but its fluid resistance is larger. The resistance of direct flow fluid is small, and it is mostly used for fluids containing solid particles or large viscosity. The right-angle valve body is mostly forged, which is suitable for smaller and higher pressure globe valves.

5, in the opening and closing process, the friction of the sealing surface is smaller than that of the gate valve, wear-resistant.

6, usually only one sealing surface, good manufacturing process, easy maintenance.

7, the electric actuator is easy to operate.

Electric globe valve, also called electric closure door, is a widely used valve, and electric ball valve is different, it is popular, because the friction between the sealing surface in the opening and closing process is small, more durable, the opening height is not large, easy to manufacture, convenient maintenance, not only for low pressure, but also for high pressure. The closing principle of the electric globe valve is to rely on the electric thrust to rotate the valve lever, so that the sealing surface of the valve disc and the sealing surface of the valve seat are closely fitted to prevent the flow of the medium. The electric stop valve only allows one-way flow of the medium and is directional when installed. The structural length of the globe valve is greater than that of the gate valve, and the fluid resistance is large, and the sealing reliability is not strong during long-term operation.
