Rotary valve for pneumatic conveying
Rotolok Limited UK
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.
