Going the extra mile for our customers is always our priority. Rush order for a critical plant shut down at an oil and gas facility in Western Canada. The transducer supplier severely delayed the shipping however our excellent engineering team found a solution within our series AT, Pneumatic Modulating Control Valve Actuator, and redesigned the already made actuator and built it in one day!

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...
