Operating principle and use
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 a good airlock is essential on cyclone and bag filter applications in order that the manufacturers quoted high dust collection efficiencies can be maintained. Airlocks are also important in the pneumatic conveying industry, where product is regulated into a pressure or vacuum conveying line while minimising air leakage.
Pressure differentials to 20psi and temperatures to 400°C (752°F) are considered the norm and extreme pressures and temperatures can be accommodated with special designs.
We offer a wide range of rotary valves in cast iron, aluminium or stainless steel.
