At what pressure should safety valves typically be set in a fuel system?

Safety valves in a fuel system are crucial components designed to prevent excessive pressure build-up that may lead to system failures or hazardous situations. The typical setting for safety valves is based on the design specifications of the system and regulatory standards that ensure safe operation.

A pressure setting of 100 psi is commonly deemed appropriate for many fuel systems. This setting is considered a balance between providing adequate pressure to ensure efficient fuel flow while also leaving a safety margin to prevent over-pressurization. At this level, the safety valve can effectively protect the system by venting excess pressure before it reaches potentially damaging levels.

When safety valves are set too low, they may not allow the system to operate effectively. Conversely, if set too high, they may not activate in time to prevent damage. Hence, a standard setting like 100 psi is widely accepted and aligns with best practices in the industry, reflecting a balance between operational efficiency and safety.
