Where would a safety valve typically be installed in a compressed air system?

A safety valve is typically installed at the air receiver in a compressed air system for several important reasons. The air receiver acts as a storage tank for compressed air, helping to stabilize the pressure within the system and providing a buffer during peak demand periods. The safety valve serves to protect the vessel from overpressure situations, which can occur due to various factors, such as compressor malfunction or excessive demand from downstream equipment.

By placing the safety valve at the air receiver, it can monitor the pressure in a centralized location, ensuring that if the pressure exceeds a predetermined safe limit, the valve can automatically release excess air to prevent a potential explosion or other hazardous conditions. This placement is crucial because the receiver is where the most significant pressure fluctuations might occur, making it the ideal point for pressure regulation and safety.

Other potential locations, such as on the compressor unit or near distribution lines, might not adequately safeguard the system against overpressure scenarios that could arise in the air receiver itself. Additionally, having a safety valve on end-use equipment may not provide comprehensive protection for the entire system, as it only addresses localized pressure issues rather than system-wide pressures managed at the receiver.
