West Germany's P.D. Rasspe Soehne has developed an improved control system for automatically closing a flow-control valve in a natural-gas pipeline when a burst occurs downstream of the valve. Unlike earlier devices, which depend upon unreliable outside energy systems to close the valve, the improved system uses pipeline pressure upstream of the burst. A differential pressure valve is connected so that both sides are impinged upon by the pressure of the natural-gas pipeline taken from a point located downstream of a flow-control valve. When a drop in pressure on that side of the flow control valve occurs, the pressure-differential valve connects the natural-gas pipeline on the other side of the flow-control valve (where the working pressure prevails) with the actuator device of the system, which in turn closes the valve.
