The anti-surge controller protects the compressor from surge by continuously calculating the distance between the compressor’s operating point and its surge limit line. The controller modulates/controls the recycle or anti-surge control valve to prevent the compressor’s operating point from reaching the surge limit while maintaining other ...

An anti-surge valve, also known as a surge-anticipating valve, is a type of control valve (surge relief valve) used in fluid systems to prevent overpressure and pressure surges that can damage equipment or cause system failure. It is typically used in systems that have rapidly changing flow rates, such as in turbocharged engines, compressors ...

The working principle of the anti-surge valve is that when the centrifugal compressor suddenly decelerates, the low pressure behind the throttle is transmitted to the pressure feedback connector of the surge valve through the surge valve ventilation hose, and the one-way cut-off diaphragm of the surge valve is opened to balance the pressure ...

Anti-surge valves, also known as surge relief or surge-anticipating valves, are crucial components in fluid systems designed to prevent overpressure and pressure surges. These valves are essential in systems with rapidly changing flow rates, such as turbocharged engines, compressors, and pumps, as they protect the system from potential damage ...
