The 10 Plus emergency shut-off valve, based on the 10 Series emergency shut-off valve, includes all the same features as the 10 Series with the addition of patent-pending SmartGuard technology, designed to contain fuel leakage at the shear groove and activate the valve to close in the event of a low-impact incident. In-house laboratory tests conducted on leading emergency shear valves show that 100 percent of the valves were prone to leak at the shear groove when subjected to a low-impact force between 282-575 ft lbs, and of this test sample, 77 percent of the valves did not close as a result of the low-impact force, neglecting to shut off the flow of fuel. This valve is said to be the only one designed to contain a shear-groove leak and close the flow of fuel in the event of an undetected low-impact break. It is UL-listed and includes a fusible link and double-poppet design.
