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. Rotary Airlock Valves typically run at very slow speeds – 5 to 26 rpm.

Many users have a “dislike” for rotary  airlock valves, 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.  Allow us to help solve your current problem by completely understanding your application and concerns.

Rotary Airlock Valves & Feeders - Standard design used for most pneumatic conveying applications.

Side Entry Rotary Airlock Valves - Design minimizes shearing and is used for non-friable products.

        Blow Thru Rotary Airlock Valves For sticky, non-abrasive products.  Low headroom, as convey pickup pan is eliminated

               Quick Clean -            For food & sanitary applications.  Remove rotor without tools.  Optional side rails.
