OPW offers emergency shut-off valve
Jun 1, 2008 12:00 PM
OPW Fueling Components has introduced a new emergency shut-off valve, the OPW 10 Plus Emergency Shut-Off Valve. Building upon the design of the company's 10 Series emergency shut-off valve, the new 10 Plus includes all of the same features as the 10 Series with the addition of its patent-pending SmartGuard technology. This technology is 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% of the valves were prone to leak at the shear groove when subjected to a low-impact force between 282-575 ft-lb.
Of this test sample, 77% of the valves did not close as a result of the low-impact force, neglecting to shut off the flow of fuel.
In a real-world situation, these types of leaks could go undetected by operators, allowing fuel to leak into sumps and thereby creating a potentially hazardous situation at the island.
The new 10 Plus, like its predecessor, the 10 Series, is UL-listed and includes these 10 Series design features:
Fusible link designed to automatically close the valve to reduce a fire hazard
Double-poppet design to provide for a safer environment in the event of a shear or sump fire
