The advantage of the gate valve is that the fluid resistance of the gate valve is small, the closing is relatively tight, the opening and closing is easier, and it also has a certain adjustment function. The disadvantage of the gate valve is that the structure is complex, the price is relatively high, a large space is required for installation, the sealing surface has relative friction when opening and closing, and impurities are easily deposited in the valve seat groove, resulting in a loose closing.
