1. Low fluid resistance. The internal medium channel of the valve body of the gate valve is straight-through. As mentioned above, the gate valve can only be fully open or fully closed. When the gate valve is fully open, the flow resistance of the medium passing through the valve body channel of the gate valve is close to 0, and the flow resistance is very small.
2. Switch operation is labor-saving. Because when the gate of the gate valve is opened and closed, the movement direction is up and down, which is perpendicular to the direction of the medium movement in the valve body channel. Compared with the cut-off valve, the opening and closing operation of the gate valve is more labor-saving.
3. Two-way circulation. The gate valve is a two-way valve, that is to say, the flow direction of the medium in the valve body channel is not limited, and the medium can flow arbitrarily from both sides of the gate valve, without affecting the normal opening and closing of the gate valve. Therefore, the gate valve is suitable for installation in the pipeline where the flow direction of the medium may change.
4. Good sealing performance. The gate valve is used to cut off the medium, so in terms of sealing performance, the sealing performance of the gate valve is better than that of the butterfly valve.
