Unlike the drop-through valve, the blow-through valve has a sealed bottom. It does not contain an exit flange like that of the flow through valve, instead it has a trough where the pneumatic conveying line connects. The feed is supplied to the valve via the inlet port, then the rotor turns and drops the feed into the trough where it is blown out into the conveying line. It is suitable for more cohesive materials like flour, milk powder, custard etc.
