Refurbishing Rotary Valve

Rotary Valves by the nature of the design have tight internal clearances and are often used as an airlock to separate two different pressure or vacuum zones. These rotary valves can handle a wide variety of powders or granules that may have abrasive or corrosive properties. As a rotary valve goes through its normal service life it eventually gets to a point that it no longer serves the needs of the application.
