There are many kinds of gate valves, for example, flanged gate valves. A flanged gate valve is connected by a flange, which is very common to be seen. A flanged gate valve is stable and reliable when used in pipelines, so a flanged gate valve is often used in high-pressure pipelines.



Features of Flanged Gate Valves
1. A flanged gate valve has compact structure, reasonable design, smooth channel and small flow resistance coefficient.
2. The sealing surface is made of stainless steel and hard alloy, so the sealing is good.
3. Flexible graphite packing is used for reliable sealing.

Advantages of Flanged Gate Valves
1. A flanged gate valve has low fluid resistance.
2. The external force required for opening and closing is small.
3. The flow direction of the medium is not restricted.
4. The scouring of the sealing surface by the working medium is smaller than that of a globe valve.
5. A flanged gate valve has simple shapes and good casting technology.

Applications of Flanged Gate Valves
As the opening and closing device to connect or cut off the medium in the pipeline, the flanged gate valve is widely used in the oil, water and steam pipelines of petroleum, chemical and thermal power plants.
