Z41H-2.5 DN1600 Gate Valve
Working Principle and Application
Among various types of valves, gate valves are one of the most widely used.
A gate valve refers to a valve whose closing member (gate) moves perpendicularly to the axis of the passage. It is mainly used to cut off media in pipelines, that is, it is used in fully open or fully closed state. Generally, a gate valve cannot be used to adjust flow rate. It can be applied to both low-temperature and low-pressure conditions as well as high-temperature and high-pressure conditions, and can be used for various media according to different materials of the valve. However, gate valves are generally not used in pipelines conveying media such as mud.
Product Features
1. Small fluid resistance, and the sealing surface is less eroded and corroded by media.
2. Relatively labor-saving to open and close. The torque required for opening and closing is small;
3. It can be used in ring network pipelines where media flows in both directions, that is, the flow direction of the medium is not restricted;
4. Simple shape, short structural length, good manufacturing process and wide application range. When fully open, the erosion of the sealing surface by working media is smaller than that of globe valves;
5. Relatively short structural length.
