Machine Guarding Rotary Airlocks. To prevent users from exposing themselves to these hazards, industry practice and safety engineering design consensus has been to install an interlock guard/cover. A guard that is interlocked with the airlock will prevent the airlock from operating if the guard is removed or disabled.

Housing & End-plates. Rotary valves are made up of 4 main parts; cylinder (or housing), end-plates, rotor, and drive package. Magnum Systems' rotary valves are made from cast gray iron, stainless steel and or Hard Chrome. The reason the housings are made out of a cast mold is the strength it adds to the design that is not possible if just fabricated.

Rotary valves typically run with efficiencies ranging between 65-85%. Product followability, pressure differential, type of feed to the valve, and rotor design can all affect this. For this instance, let's estimate a 70% efficiency. To determine rotor speed, we need to select a speed that is at the higher end of the valve's capable range ...

An airlock is a transitional space that typically has two doors in series to separate a controlled environment (such as cleanroom, lab, operating room, or isolation room) from a corridor, or vice versa. The two doors should be interlocked to avoid being opened at the same time. An airlock area is often ventilated with filtered supply air, with ...
