1. It offers small fluid resistance as the inner media channel of the body is straight. It flows though the valve which does not hampers the direction of the flow.

2. Gate valves offer an unobstructed media flow from any direction of the valve body. It does not decrease pressure which makes it suitable for pipeline where the flow direction may change.

3. The overall structure length of gate valves is shorter than globe valves. The valve clack aligns with the valve body, thus making the structure length of gate valves shorter than globe valves.

4. The seal functioning is quite good thus, making it less eroded while it is open.

5. As compared to globe valves, the erosion of sealing surface is lighter.

The valve body is simple and easy to operate. It features a good casting process which offers a wide range.
