Diverter Valves
In-line diverter valves are designed to either allow material to pass through or to divert material to the destination with the demand. By putting one of these diverter valves at each receiver, material from the source can not accidentally end up in the wrong destination because all of the material called for is forced to pass by the receivers with no demand signal and be diverted only to the receiver with the demand signal. They are intended to eliminate blow-by of material and therefore contamination.
There are multiple designs and some are better than others.
Some designs depend on a standard "Y" with a diverter valve operated by compressed air . These may still not force all pellets to the desired destination because there is a small "hang-up" point.
A second type of diverter has a unique design. The BiVerter, has no "hang-up points", therefore no contamination. They can be used in common line or dedicated line systems.
