For granular fillers, valves that allow for precise control of the filler flow rate and provide sealing
Thread Content
For granular fillers, what valves are recommended that can precisely control the flow rate of the filler and provide good sealing? The filler particles are around 2-4 mm in size; butterfly valves and ball valves tend to trap the material, and the discharge capacity of unloaders is limited. Therefore, I would like to ask for any suitable valve recommendations
There is a type of rotating discharge valve that has the appearance of a ball valve, but one side of it is shaped like a bowl with a hollow interior; it discharges material in ‘bowlfuls’ as it rotates, and the amount of material discharged is determined by the rotation speed and the size of the bowl. Many years ago, Hefei General Research Institute conducted on-site surveys of imported valves at our location
Is there a link I can check? I can’t find that bowl-shaped one you’re talking about here
There are no diagrams for the operation; the operating method is similar to that of a rotary feeder or rotary valve. The core of the valve has the shape of a ball valve, while its interior is bowl-shaped
Type C ball valve, high density, adjustable, resistant to jamming
Can it be used for particles that easily generate dust? It’s similar to the particle size mentioned in my question
The C valve is indeed very useful. For media that tend to crystallize, form scale, or develop scars, it is recommended to use ceramic C valves. For ordinary media, ceramic ball valves are more than sufficient, and ceramics possess natural resistance to wear and erosion.
