The receiving valve is a material shut-off system used in dense phase pneumatic conveying. Installed above silos and hoppers, it allows several destinations to be fed with a single pipeline.

The receiving valve can be either through or terminal.
The pass-through valve allows both the material to pass through the pipe (if closed) and the product to fall into the destination below (if open), while the terminal valve is installed at the end of the route to allow the material to descend into the silo.
The outlet diameter of the receiving valve is determined by the diameter of the conveying pipeline.
