The Scale Divert Valve features precise tolerances, in-line cleaning, fast tool-free disassembly and air-controlled operation. The design allows user to easily divert pneumatically conveyed materials to bulk storage bins, scale hoppers, process hoppers and more. A rotating assembly inside the valve determines if air and material pass straight through or are diverted. In the non-divert position, a rotating assembly inside the valve is turned so air and material pass straight through completely unrestricted. In the divert position, the rotating assembly is turned so air and material entering the valve are directed downwards by the diversion paddle.
