What is the role of a safety valve in compressor systems?

In compressor systems, the primary role of a safety valve is to prevent excess pressure build-up. Compressors work by increasing the pressure of gases or air, and if the pressure exceeds safe limits due to factors such as failure in the control system or mechanical issues, the safety valve acts as a critical safety feature. It automatically opens at a predetermined pressure setpoint, allowing some of the compressed air or gas to escape, thus relieving excess pressure. This action helps to protect the compressor and associated piping and equipment from potential damage, explosions, or other hazardous situations that could arise from over-pressurization. By ensuring safe operation, the safety valve plays a crucial role in maintaining the integrity and safety of compressor systems.
