The main advantages of stop valves include simple structure, easy manufacturing and maintenance, small working stroke and short opening and closing time, good sealing, small friction between sealing surfaces and long service life. In addition, the stop valve has large fluid resistance, requires large force when opening and closing, is not suitable for media with particles, high viscosity, easy to coke, and has poor adjustment performance.
These advantages of stop valves make it perform well in a variety of fluid control scenarios. It has a simple structure, is easy to manufacture and maintain, has a small working stroke and short opening and closing time, has good sealing, small friction between sealing surfaces, and has a long service life. However, it should be noted that the stop valve has large fluid resistance, is not suitable for certain specific media, and has poor adjustment performance.
