Gate valve [2] as a lower level of the valve, more common.
First, the advantages of gate valve [3]
1, fluid resistance is small.
2, the opening and closing of the required external force is small.
3, the flow of media is not limited.
4, when fully open, the sealing surface by the working medium erosion than the cutoff valve smaller.
5, the shape is relatively simple, casting process is better.
Ii. Disadvantages of gate valve [4] 1, the appearance of size and opening height are larger.
The installation requires a large space.
2, the opening and closing process, the sealing surface has a relative friction, easy to cause bruising phenomenon. 3, gate valve [5] generally has two sealing surface, for processing, grinding and maintenance to add some difficulties
