The fluid resistance is small, the sealing surface is scoured and eroded by the medium is small.
Open and close less effort.
The flow direction of the medium is not restricted, not disturbing the flow, not reducing the pressure.
Simple shape, short structure length, good manufacturing technology, wide range of application.
Disadvantages of gate valves are as follows:
It is easy to cause erosion and abrasion between sealing surfaces, and it is difficult to maintain.
The external size is large, the opening needs a certain space, the opening and closing time is long.
The structure is more complex.
