American standard welding stop valve
I. Structural Features
A globe valve is a commonly used shut-off valve, mainly used to connect or cut off the medium in the pipeline. The main advantages of globe valves are:
1. Compared with gate valves, globe valves have a simpler structure and are easier to manufacture and maintain.
2. The sealing surface is not easily worn or scratched, with good sealing performance and a long service life.
3. The stroke of the disc during opening and closing is small, the opening and closing time is short, and the valve height is small.
4. The end adopts welding, making the sealing more reliable.
