Selection & Application FAQ
This circular flange stainless steel rotary valve supports sealed feeding and smooth connection with round pipelines, pneumatic conveying systems and powder process equipment.
Where is a circular flange rotary valve used?
It is commonly used below silos, dust collectors, mixers and pneumatic conveying pipelines that require round inlet or outlet connection.
How is the valve sized?
Sizing depends on target capacity, material bulk density, rotor volume, speed, pressure difference and installation dimensions.
Can FUWEI adjust the connection standard?
Yes. Flange drilling, diameter, face-to-face length and motor position can be customized to match existing equipment.
