Which device is designed to protect the air tank and system from too much pressure?
Note
The correct answer is: Safety valve. A safety relief valve is installed in the first tank that the air compressor pumps air into. A safety valve protects the tank and system from too much pressure by opening up at 150 psi. The governor controls when the air compressor will pump air into the air storage tanks. An alcohol evaporator puts alcohol into the air system to help reduce the risk of ice in cold weather.
