In this circumstance, a blow-through design could put too much resistance on the product and cause it to break down, while the obstruction-free convey transition under a drop-through design may better protect the product’s integrity.

Another benefit of drop-through rotary valves is in applications were cleaning the interior of the valve is essential for product safety. With a drop-through design the internal area of the rotary valve can be accessed without dismantling convey line connections. This makes cleaning quicker and easier.
