What is the primary purpose of safety valves in fuel systems?

The primary purpose of safety valves in fuel systems is to prevent backflow and allow safe venting of vapors. Safety valves are critical components designed to maintain the integrity and safety of fuel systems. They help to manage pressure build-up in fuel lines and storage, ensuring that any excess pressure can be safely released. This function is essential in preventing hazardous situations that could arise from over-pressurization, such as leaks, spills, or explosions.

By ensuring that vapors can be vented safely, safety valves contribute significantly to minimizing the risk of ignition and allowing for effective system operation. The prevention of backflow also protects the fuel supply from contamination and maintains the proper flow direction, allowing for efficient fuel delivery and system reliability.
