The Axial Flow Control Valve is design for special applications requiring high flow capacity, the precise control from a linear motion closure member, and reduced turbulence and vibrational effects.

An ideal application is centrifugal compressors, as commonly used in gas transmission compressor stations, petro-chemical installations, which display a potentially destructive phenomenon called ãsurgeà. Surge is a reversal of high velocity flow that can have catastrophic consequences to the compressor. To protect the compressor, the anti-surge valve control valve must open very fast and eject the surge. These valves have to be fast acting but also have high capacity and anti-noise designs.
