Manual Gate Valve
The knife gate valve is also known as a manual knife gate valve. The knife gate valve is a valve in which the gate and seat are always in close contact and sealed. The principle is that there is a circular opening with a diameter on the gate plate that opens and closes through the gate plate. This causes the circular opening on the gate plate to completely separate from and coincide with the diameter. The advantage of this valve is that there are no grooves in the diameter of the valve body, the medium is not blocked and jammed, and it has full-through flow characteristics. Its sealing structure can be divided into soft sealing structure and hard sealing structure.
