Safety valves are specifically designed to protect systems from excessive pressure by opening to release pressure when it exceeds a predefined limit. In aircraft, these valves play a critical role in maintaining safe operating conditions by preventing the risk of component failure or catastrophic events caused by overpressure. Once the pressure drops back below the safety threshold, the valve will close, allowing the system to return to normal operation.

By using safety valves in an aircraft, engineers ensure that systems such as fuel, hydraulic, and pneumatic systems operate safely and efficiently without the risk of over-pressurization.
