Abstract:
1. A remotely operated shutoff valve system, comprising: a safety valve for selectively terminating flow through the safety valve, the safety valve including an electromagnet for holding the safety valve open, and a swing plate for closing the safety valve while providing a low restriction to fluid flow when the safety valve is open; an electrical power supply for powering the electromagnet; a shutdown switch; an electrical conductor extending between the shutdown switch, the power supply, and the electromagnet, the electrical conductor including an electrical connector spaced along the electrical conductor, and a flow line between a towing vehicle and a towed vehicle being separable during a separation of the towing vehicle from the towed vehicle, the safety valve being positioned along the flow line; and the safety valve automatically closing in response to one of activation of the shutdown switch or the loss of electrical power to the electromagnet, wherein the safety valve includes a linearly movable member, such that the electromagnet is adjacent one end of the linearly movable member and a linearly movable pin for holding the swing plate open is adjacent the other end of the linearly movable member, wherein the linearly movable member is a U-shaped member.
