he 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 “surge”. 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.

Due to the high capacity of the axial flow valve, several stages can be used in order to reduce the noise level of these applications. The crank-lever system design of the Axial Flow Control Valve, transform a small torque into a big thrust, allowing the valve to require smaller actuator sized, which in consequence increases precision and speed of control.

These control valves can be equipped with SAMSON GROUP actuators and valve accessories such as positioners, limit switches, and solenoid valves.


  • Smooth and precise control that is friction free, backlash free, and unaffected by dirt
  • Environmentally safe with zero emissions due to rotating shaft
  • Drive mechanism multiplier effect gives maximum thrust when it is required
