If controlled feeding from or into silos and hoppers in a very confined space is required Rotary Valves are the ideal solution.
The sealing of negative pressure cyclone and dust filter outlets is the other classic application.
RVS-type Blow-Through Rotary Valves have been developed in accordance with the criterion of maximum scope in application.
They have been designed for the controlled discharging of powders or granular materials from silos, bins, hoppers, cyclones or dust collectors into low- and medium-pressure pneumatic conveying lines.

Rotary Airlocks - Standard Rotary Valves
The prime function of a rotary valve is to regulate the flow from one chamber to another while maintaining a good airlock condition. The product is mainly in dry powder or granular form.
In the dust filtration field good airlocks are essential on cyclone and bag filter application in order that the manufactures quoted high dust collection efficiencies can be maintained. Airlocks are also important in the pneumatic conveying industry, where product is regulated into a high pressure conveying line while minimising air leakage.
With Rotolok there are no double standards, all our standard valves are precision machined for close tolerances and minimal eccentricities Pressure differentials to 20psi and temperatures to 400°C.
Extreme Pressures and Temperatures can be accommodated with special designs, if your application requires such considerations contact Rotolok Engineering team.

High pressure rotary feeders are mainly used for the discharge (dosing) of pellets and powders from silos. Furthermore they are used as a feeding device in pneumatic dense phase and dilute phase conveying systems with a differential pressure up to 4 bar (g).
High Pressure Rotary Feeder Type HDS
The HDS rotary feeders are mainly used for the discharge (dosing) of pellets and powders from silos. Furthermore they are used as a feeding device in pneumatic dense phase and dilute phase conveying systems with a differential pressure up to 3.5 bar (g).
|
|
|
The medium pressure rotary feeders are mainly used for the discharge (dosing) of pellets and powders from silos and hoppers. Furthermore, they serve as feeding devices in pneumatic dilute phase conveying systems with a differential pressure up to 2.0 bar (g).
