Structural features:
Unidirectional flow: API globe valve only allows the medium to flow in one direction, the installation of directional.
Fluid resistance: compared with the gate valve, globe valve fluid resistance is greater.
Performance Advantages
Good sealing performance: rely on the valve stem pressure to make the valve sealing surface and the valve seat sealing surface close to prevent the flow of media, can effectively prevent the leakage of media, suitable for the sealing requirements of the higher occasions.
Working stroke is small: opening height is not large, short opening and closing time, operation is relatively simple and fast, can quickly realize the medium of on-off control.
Wide range of applicable pressure: not only for low-pressure, but also for high-pressure, can meet the needs of different pressure levels of pipeline systems.
