Rotary Valve

The main function of a Blow Through Rotary Valve is to regulate the flow of material from onechamber to another while maintaining a good airlock condition. The materialor product being handled is usually dry free flowing powder, dust orgranules.The granule type of product, especially if it is a plastic type,polyethelene or nylon etc., does not shear easilyand consequently, withoutconsiderable care thestandard drop-through type ofvalve leads to valve seizureand also considerable shockloadings.To minimize these problems the Offset Rotary Valve ensures lower pocket fillage as its design meansthat the rotor is still being filled in the upward cycle with the pellets falling away at the shear point.Similarly, the pelican beak distributes the product across the full width of the rotor.
