Gate valve refers to the valve whose closing member (gate) moves along the vertical direction of the channel axis.
It is mainly used to cut off the medium on the pipeline, that is, fully open or fully closed.
In general, gate valves cannot be used to regulate flow.
It can be applied to low temperature and low pressure as well as high temperature and high pressure, and can be used for various media according to the different materials of the valve.
But gate valves are generally not used in pipelines for conveying mud and other media.

Application range

Cast steel gate valve is suitable for cutting off or connecting pipelines in various industries such as petroleum, chemical, pharmaceutical, fertilizer, electric power industry, etc., with nominal pressure PN1.6~6.4MPa and working temperature -29~600℃ The medium cannot be adjusted or throttled.

Structural features and advantages:
1) Small fluid resistance;
2) The torque required for opening and closing is small;
3) It can be used on the ring network pipeline where the medium flows in two directions, that is to say, the flow direction of the medium is not restricted;
4) When fully opened, the erosion of the sealing surface by the working medium is smaller than that of the globe valve;
5) The body structure is relatively simple, and the manufacturing process is better;
6) The length of the structure is relatively short: Because the gate valve has many advantages, it is widely used in China. Usually, the pipeline with DN ≥ 50MM is used as the device for cutting off the medium.
