Electric shut-off valve

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.

Advantages of electric shut-off valves

1. The structure is simple, and manufacturing and maintenance are relatively convenient.

2. Small working stroke and short opening and closing time.

3. Good sealing performance, low friction between sealing surfaces, and long service life.

4. The structural forms of the globe valve body include straight through, direct flow, and right angle. The straight through type is a common structure, but its fluid resistance. Direct flow fluids have low resistance and are often used for fluids containing solid particles or with high viscosity. The right angle valve body is mostly forged, suitable for globe valves with smaller diameter and higher pressure.

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

6. Usually there is only one sealing surface, with good manufacturing technology and easy maintenance.

7. Electric actuators are easy to operate.
