Blow Through Rotary Valve is used to deliver bulk materials in pneumatic conveyor systems.Blow through rotary valves consist of a tubular cast iron or stainless steel casing, a horizontally mounted rotor with a certain number of oblique V-shaped cross section compartments, a drive unit and a casing cover at each end.
Blow through rotary valve has been specifically designed to meet the rugged demands of the pneumatic conveying industry. It is a natural extension of the rotary valve in that both are used to regulate the flow of dry powders, dusts and granular products, while maintaining an airlock condition.
However, the blow through rotary valve offers distinct advantages in that it introduces high pressure conveying air through the valve body and rotor pocket, ensuring a high efficiency throughput with a low effective pressure drop.
Function
Two compartments at a time of the continuously turning rotor are filled up with material through the inlet at the top of the rotary valve. After less than half a turn the material falls through the bottom opening into an air stream passing through a pneumatic conveying pipeline connected with the bottom part of the rotary valve.
