Fast response for large valves
22 April 2014
To overcome problems associated with applications where process control systems require larger valves control, Samson Controls has developed a control valve positioner package which ensures precise positioning with fast response times, over the entire operating range of, for example strokes of 60mm and greater.

The package consists of a positioner and a special hook up of several volume boosters with different air output capacities which perform this task. Closing and opening times of less than two seconds can be achieved over the entire positioning range.
The flow control applications where the Samson package has been successful is for compress or bypass valves (anti-surge valves) as well as in petrochemical applications involving adsorption processes in moving-bed adsorbers.
