More Information
In simple terms, surge in a compressor is the phenomenon that occurs when the flow through the entire compressor is reversed intermittently.It is critical to avoid this phenomenon from happening since it is catastrophic for the integrity of the compressor as it will severely damage it. to prevent surges from happening, systems normally use anti-surge valves.
For such critical operation, the valve must be completed with controllers that use the suction and discharge pressure and temperatures to determine the flow at which the condition of surge will occur.It is crucial for such valves to be operated by actuators that can achieve extremely fast stroking times, high frequency of operation, minimal dead time and overshoot.
Depending on the availability and reliability of the power supplies sources of your application, Cowan Dynamics has developed solutions within our product lines of Pneumatic and Electro-hydraulic actuators that allow opening times as fast as 0.5 secs, dead time of 0.3 seconds and an overshoot of 0.4 of 1% of the stroke.
Our team of technical experts can assist you to select the best solution for your application.
