swing type check valve are shutoff pieces (discs) that move along the center line of the seat. The globe valve is mainly used for cutting off in pipelines. Globe valves have the following advantages:
1. In the process of opening and closing the sealing surface friction is smaller than the gate valve, wear - resistant.
2. Small opening height.
3. Usually only one sealing surface, good manufacturing technology, easy to maintain.
Globe valves are commonly used, but due to the large opening and closing torque and long structural length, the general nominal diameter is limited to DN less than 200mm. The fluid resistance loss of the globe valve is large. This limits the wider use of globe valves
