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.

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 (752°F) are considered the norm and extreme pressures and temperatures can be accommodated with special designs. If your application requires such considerations contact the Rotolok Engineering team.

Rotolok Rotary Valves and Airlocks have ATEX Covered

Following successful completion of the rigorous testing process Rotolok can offer a complete range of Rotary Valves certified as suitable for use as an explosion barrier to a maximum of 10bar and for explosion isolation for St1 and St2 dusts.

The picture shows what 10 bar explosion pressure can do to 10mm thick carbon steel rotor vanes of inadequate design.

Due to careful design of the internal components the overall dimensions are very similar to our standard range of valves and we can offer a selection of optional features such as purged shaft seals, scalloped rotor pockets and staggered rotor pockets without the throughput being greatly reduced or the barrier efficiency being affected.
