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 of granular form.

In the dust filtration field good airlocks are essential on cyclone and bag filter application 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 high pressure conveying line while minimizing air leakage.

With Rotolok there are no double standards, all our standard valves are precision machines for close tolerances and minimal eccentricities Pressure differentials to 20psi and temperatures to 750 ºF.

We have made specials to handle temperatures covering 2200 ºF and pressures to 350psi.
