1. Gate valve is one of the commonly used block valves, which is mainly used to connect or block the medium in the pipeline; The gate valve is applicable to a wide range of pressures, temperatures and diameters, especially for medium and large diameter pipelines.

2. The wedge type rigid single ram is simple in structure, small in size and reliable in use. It is suitable for various medium and pressure environments at normal and moderate temperatures. It is widely used in water supply and drainage, gas, electric power, metallurgy, petroleum, chemical industry, light textile, urban construction and other industries, and is used for opening and closing on pipelines of steam, water and oil media.

3. The fluid resistance is small. The medium channel inside the gate valve body is straight through, and the medium does not change its flow direction when flowing through the gate valve, so the flow resistance is small.

4. It is easier to open and close. When opening and closing, the ram movement direction is perpendicular to the medium flow direction. Compared with the globe valve, the opening and closing of the gate valve is labor-saving.

5. The medium flow direction is generally unrestricted. The medium can flow through both sides of the gate valve in any direction to achieve the purpose of connection or cutoff. It is easy to install and applicable to the pipeline where the flow direction of the medium may change.
