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.
