The function of a pneumatic safety valve is critical for the safe operation of pneumatic systems. This valve is designed to monitor and respond to pressure levels within the system. Specifically, it prevents excessive pressure buildup, which can lead to dangerous situations such as equipment failure or even physical harm to users. When the pressure reaches a predetermined threshold, the safety valve activates and releases air from the system, effectively lowering the pressure back into a safe operating range.

By ensuring that pressure does not exceed safe limits, the safety valve plays a vital role in maintaining system integrity and safety. This functionality is particularly important in various applications where pressure fluctuations can occur, and the consequences of failure can be severe. The other options, although relevant to pneumatic systems, do not describe the specific role of a safety valve: filtering contaminants, regulating air volume, and maintaining temperature are managed by different components or systems altogether.
