FV/MFV Series Flow Control Values
Enjoy Complete and Precise Flow Control!
The FV and MFV Series control valves attach to the discharge openings of bins, hoppers or chutes to control the amount of material flowing through. Featuring a sleeve that opens and closes in a concentric circle like a camera aperture, these unique valves are perfect for distributing, mixing, sampling, bagging, and otherwise processing ultra-fine powders. The FV valves open and close manually with an easy-to-operate handle, while the MFV valves come equipped with a motor that will adjust the aperture with the flick of a switch. Both the FV and MFV valves are available in aluminum or stainless steel to suit the application.

Connection Diagram
Example of Application
Flow control
Attached to the outlet of a hopper, the flow rate is adjusted by "squeezing". Essential for mixing, blending, bagging, and other processes.
Easy adjustment from fully open to fully closed (FV type)
Valves for easily damaged materials (e.g. tablets)
For mixer input port
