2.Structure:
3.Main Features:
1.Gate valve refers to the valve that opens and closes (Wedge) in the vertical direction of the medium flow direction (through the axis) to achieve opening and closing.
2.The gate valve is mainly used as a cutting fluid on the pipeline, to fully open or fully closed.
3.Gate valves can be used in low temperature, low pressure, high temperature and high pressure, and also could be used for a variety of different fluid depending on the valve material.
4.The gate valve is opened and closed by the rotation of the stem nut (meaning the nut does not move the stem).
