Aerodyne - Model Rhino R -High Capacity Rotary Valve
The Aerodyne High Capacity Rhino Rotary “R” Valve is designed for continuous discharge of free-flowing, low-abrasive dry solids in gravity flow or low-pressure systems. Widely used in applications such as the bottom of dust collector hoppers, the Rhino Rotary “R” Valve’s steel plate construction gives it a distinct advantage in quality and flexibility over cast valves.
- Heavy duty steel plate fabrication
- Open rotor
- EPDM wipers
- Can handle temperatures to 175°
- Operating Pressure – ±20″ W.C.
Also known as a rotary airlock valve, a rotary valve is used in a dry solids material handling system to control the feed or discharge of free-flowing bulk material without compromising the negative or positive air pressure used in the system.
A rotary valve’s design is similar to a revolving door by which one might enter a building: material must pass through a rotating chamber in order to reach the opening on the other side. The turning vanes of the rotary valve are tightly spaced to the valve walls, creating an airlock. Vanes may be tipped with hardened metal or flexible wipers. This rotary valve is motor driven; the motor and its controls must be part of the specification.
Common applications for rotary valves include pneumatic conveying, gravity conveying, gravity discharging, and volumetric metering. With these applications, they are commonly used with bag house hoppers, storage bins, and dust collection systems.
The seal of this style valve is not perfect and is therefore suited to low and moderately pressurized systems where a small air leak is acceptable. Its design is compatible with high temperature applications, and models are available for this purpose. Heavy duty valves, such as Aerodyne’s Rhino Rotary H Valve™, are available that can process abrasive and stringy materials.
