What is an anti-surge valve?

An anti-surge valve is specifically designed and installed to protect the compressor from reaching its surge point. The valve is in the system, in a by-pass that connects the inlet and the outlet of the compressor. In normal operation, this valve remains closed, however, if the surge is detected, it quickly opens to maintain a minimum flow and directs the backflow to the outlet of the compressor to avoid damages. 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 minimal overshoot. What is compressor surge?  In...
