ABSTRACT:
An emergency discharge control system for use with a cargo tank motor vehicle and a primary storage tank for remotely terminating the flow of product from the cargo tank of the cargo tank motor vehicle and the storage tank in an emergency situation is provided. The system includes a cylinder having a piston rod connected to a cable assembly of the cargo tank motor vehicle and a cylinder having a piston rod connected to a cable assembly of the primary storage tank for actuating the respective cable assemblies and closing the vapor valves and the liquid valves of the cargo tank and the primary storage tank. The piston rod is extended by passing pressurized fluid into the cylinder. A valve is interposed between the cylinder and a source of the pressurized fluid for controlling the flow of the pressurized fluid to the cylinder. A receiver mounted on the cargo tank motor vehicle is electrically connected to the valve and sends an electric signal to the valve so as to cause the valve to open and permit the pressurized fluid to pass to the cylinder in response to receiving a shutdown signal from a hand-held transmitter.
