Blow Through rotary airlock valve
The Blow Through Rotary Airlock Valve is used in pneumatic conveying of positive pressure applications only. Instead of a typical outlet, blow thru rotary airlocks include two ports on the sides of the valve near the bottom. The conveying line pipe connects directly to the valve, with the air stream flowing through the rotor pockets. This design is very efficient, and works well on materials that tend to hang up in the rotor pockets. However, this valve is not recommended on abrasive products as the vanes will quickly wear. This unit is also very helpful in applications that have height limitations. Convey line adapters are provided to suit the application.
Blow through rotary valves are used in positive pressure pneumatic transport systems. They are suitable for transferring sticky powdered materials. The material enters from the top and exits from side , material blown into conveying pipe.
