Rotary Airlock Valves are used to introduce dry materials into a pressure conveying line “locking” the high-pressure (0-25 psig) air below the valve, thereby allowing material to be introduced into the conveying line.
A rotor, 6-12 vanes, delivers product on a continuous basis to the conveying line. The rotor shaft is supported by two externally located bearings, which is a potential point of product leakage. Airlocks typically run at very slow speeds – 5 to 26 rpm.
Many users have a “dislike” for airlocks, as they can be a source of high maintenance or unexpected breakdowns. Although high pressure, abrasive applications are difficult for any supplier, many problems experienced by users are a result of the wrong features being utilized for an application.
