A relief valve on a dry system located between the compressor and control valve shall be set at how many psi in excess of maximum air pressure in the system?

The appropriate setting for a relief valve on a dry system, positioned between the compressor and control valve, is essential for ensuring the system's safety and efficiency. Setting the relief valve at 10 psi above the maximum air pressure in the system serves to provide an effective safeguard against potential overpressurization.

This 10 psi increment allows for a buffer that can accommodate slight fluctuations in air pressure due to temperature changes or minor adjustments in the compressor's operation. If the relief valve were set too close to the maximum allowable air pressure, there would be a risk of the valve frequently engaging, which could lead to unnecessary air loss and possible disruptions in the function of the dry system.

The 10 psi setting also aligns with industry standards and best practices, which emphasize the importance of safety margins in pressurized systems. This ensures that the valve operates as intended during abnormal situations without compromising system integrity. Having this safety setting in place is crucial to prevent damage to the system components or the environment.
