Accumulator: An accumulator is a device that stores energy in the form of compressed air. In a pneumatic system, an accumulator can be used to provide a backup source of air pressure in the event of a power outage. This can help to ensure that the system can still operate safely, even if the power is lost.
Pressure relief valve: A pressure relief valve is a device that releases excess air pressure from a pneumatic system. In the event of a power outage, a pressure relief valve can help to prevent the system from becoming over-pressurized, which could lead to damage.
