Advantages of globe valves:
1. It has the lowest flow resistance (actually 0);
2.It can be used reliably in corrosive media and low boiling point liquids because it can not be stuck in
working (without lubricant).
3.Full sealing can be achieved in a wide range of pressure and temperature.
4.Quick start-up and shut-down can be realized. The start-up and shut-down time of some structures
is only 0.5-0.1s, so as to ensure that they can be used in the automation system of the test bed. When
the valve is opened and closed quickly, there is no impact in operation.
5.The spherical closure can be positioned automatically at the boundary position.
6.The working medium is reliable in sealing on both sides.
7.When fully open and fully closed, the sealing surface of the sphere and seat is isolated from the me-
dium, so the medium passing through the valve at high speed will not cause the erosion of the sealing
8.Compact structure and light weight, it can be considered as the most reasonable valve structure for
cryogenic medium system.
9.The valve body is symmetrical, especially the welded valve body structure, which can well withstand
the stress from the pipeline.
10.The closing part can withstand the high pressure difference when closing.
11.Ball valves with fully welded body can be buried directly underground, so that the inner parts of the
valves are not eroded. The maximum service life of the valves can be up to 30 years. They are the mo-
st ideal valves for oil and natural gas pipelines.
