Globe Valve Characteristics
- Jan 10, 2019 -

Compared with another commonly used cut-off type valve in industrial production, the shut-off valve is structurally simpler than the former, and is easy to manufacture and repair. In terms of service life, the sealing surface of the shut-off valve is not easy to wear and scratch, and there is no relative sliding between the valve flap and the sealing surface during the valve opening and closing process, so the wear and scratch on the sealing surface are small, so the sealing is improved. The service life stop valve of the auxiliary service has a small valve stroke during the full-closed process, and its height is relatively small compared to the alarm valve. The disadvantage of the shut-off valve is that the opening and closing torque is large and it is difficult to achieve rapid opening and closing. Because the flow passage in the valve body is relatively tortuous, the fluid flow resistance is large, and the fluid power is greatly lost in the pipeline.
