1. Small fluid resistance Because the internal medium channel of the gate valve body is straight, the medium does not change its flow direction when flowing through the gate valve, so the fluid resistance is small.
2. The opening and closing torque is small, and the opening and closing are more labor-saving. Because the direction of the gate movement is perpendicular to the direction of the medium flow when the gate valve is opened and closed, the opening and closing of the gate valve is more labor-saving compared with the stop valve.
3. The flow direction of the medium is not restricted, and the medium can flow in any direction from both sides of the gate valve without disturbing the flow and without reducing the pressure. It is more suitable for pipelines where the flow direction of the medium may change.
4. The structure length is shorter because the gate of the gate valve is placed vertically in the valve body, while the valve disc of the stop valve is placed horizontally in the valve body, so the structure length is shorter than that of the stop valve.
5. Good sealing performance, the sealing surface is less eroded when fully opened.
6. When fully open, the sealing surface is less eroded by the working medium than the stop valve.
7. The shape is relatively simple, the casting process is good, and the application range is wide.
