Gate valves have the characteristics of low fluid resistance, minimal impact erosion on the sealing surface, no change in the flow direction of the medium, no disturbance to the flow, small pressure array, and small opening and closing torque. They are suitable for a wide range of pressures and temperatures and are a common type of shut-off valve.

Globe valve is a commonly used shut-off valve used to cut off or connect media in pipelines, and is generally not used to regulate flow. Globe valves can also be used as opening and closing valves, but due to their high pressure drop, they are usually limited to applications where the valve is normally closed and pressure drop is not a significant factor when the valve is open.

The check valve is commonly used as the bottom valve of a pumping device to prevent water from flowing back. When used in combination with a globe valve, the check valve can provide safe isolation. The disadvantage is high resistance and poor sealing when closed.

Ball valve can also be used for fluid regulation and control, among which the hard sealed V-shaped ball valve has strong shear force between its V-shaped core and the metal valve seat of the welded hard alloy, especially suitable for media containing fibers, small solid particles, etc.

A valve specially used in low-temperature medium systems (such as liquid oxygen, liquid nitrogen, liquid argon, liquefied natural gas, etc.). Its main function is to open and close the medium in the pipeline to achieve reliable fluid control.
