The application of the Aluminum Shut-Off Valve is very wide, and the Aluminum Shut-Off Valve is used in many occasions. However, according to the different structure of the stop valve, the applicable occasions are also different.
1. Needle globe valve
It is used for precise flow control. The valve disc is usually made into a whole with the valve stem, and it has a needle makeup head that matches with the valve seat and has a very high precision. In addition, the thread pitch of the stem thread of the needle globe valve is smaller than that of the ordinary globe valve. Under normal circumstances, the size of the seat hole of the needle globe valve is smaller than the pipe size. Therefore, it is usually only applicable to pipelines with small nominal diameters, and is more commonly used for sampling valves.
2. Direct current globe valve
The valve stem and the passage of the direct flow stop valve are at a certain angle, and the seat sealing surface and the inlet and outlet passages are also at a certain angle. The valve body can be made into an integral type or a separate type. The valve body separate type globe valve uses two valve bodies to sandwich the valve seat in the middle, which is convenient for maintenance. This kind of shut-off valve makes the fluid hardly change the flow direction, and the flow resistance is the smallest in the shut-off valve. The valve seat and disc sealing surface can be welded with hard alloy to make the entire valve more resistant to erosion and corrosion, which is very suitable for pipeline control in the alumina production process, and is also suitable for pipelines with coking and solid particles.Aluminum Shut-Off Valve is your good choice.
