Abstract: A valve control system comprises a programmable electronic controller. The programmable electronic controller is configured to provide an emergency actuation signal to a motor upon receiving an emergency close signal. The programmable electronic controller is configured to provide a test actuation signal to the motor upon receiving a test close signal. The valve control system further comprises a gas detection input configured to receive a gas detection signal. Receipt of the gas detection signal at least partially meeting a first criterion causes the emergency close signal to be supplied to the controller. The valve control system further comprises a user interface configured to provide the controller with the test close signal in response to a user input. The valve control system further comprises a low battery input configured to receive a low battery signal. Receipt of the low battery signal causes the emergency close signal to be supplied to the controller.
