The stem and channel of the Y-shape slurry globe valve are at a certain angle, and the valve seat sealing surface is also at a certain angle to the inlet and outlet channel, and the valve body can be designed as integral and split type. For split slurry globe valve, two valve bodies to clamp the valve seat in the middle for easy maintenance. This type of stop valve allows the fluid to hardly change direction , flow resistance is minimal . The seat and disc sealing surface can be welded with cemented carbide, making the entire valve more resistant to erosion and abrasion, which is very suitable for pipeline control in the alumina production process, but also suitable for pipelines with coking and solid particles.

In the pipeline of the desiliconization workshop in the production of alumina Bayer, it is advisable to choose a Y-type slurry globe valve with split valve body, a removable valve seat, and a cemented carbide sealing pair.
