U403 Emergency shut-valve
U403 Series Emergency Shut-off Valve are installed on fuel supply lines beneath at grade level to minimize hazards associated with collision or fire at the dispenser. If the dispenser is pulled over or dislodged by collision, the top of the valve breaks off the flow of fuel. Single-poppet models shut off supply flow, while double-poppet models shut off supply as well as prevent release of fuel from the dispenser's internal piping. The base of the Emergency Valve is securely anchored to the concrete dispenser island through a stabilizer bar system within a U-Bolt Assembly. Valve inlet (bottom) connection are female pipe threads and outlet (top) connections are available with female threads, male threads, or a union fitting. Other options include suction system models with a normally closed secondary poppet which maintain prime, and models with external threads on inlet body which connect to secondary containment system.

Fire Protection- a fusible link trips the valve closed at 75 to shut off fuel
supply to the dispense.
Integral Test Port - a 3/8" Test Port allows the piping system to be air tested
without breaking any piping connection.
Low-Profile Tops- Female and Union-top double-poppet valves have a low-profile top to allow upgrading from single-poppet valves without changing existing piping.

ft in economic strength since the emergence of the United States more
than a century ago. As developing countries and the former Soviet block have embraced market-friendly economic
reforms and opened their borders to trade and investment, more c fuel dispenser ountries are industrialising than ever before�
and more quickly. During their industrial revolutions America and Britain took 50 years to double their real incomes
per head; today China is achieving that in a single decade. In an open world, it is much easier to catch up by
adopting advanced countries technology than it is to be an economic leader that has to invent new technologies in
order to keep growing. The shift in economic power towards emerging economies is therefore likely to continue.
This is returning the world to the sort of state that endure fuel dispenser d throughout most of its history. People forget that, until
the late 19th century, China and India were the world s two biggest economies and today s “emerging economies� fuel dispenser
accounted for the bulk of world production.
Fear or cheer?
Many bosses, workers and politicians in the rich world fear that the success of these newcomers will be at their
own expense. But rich countries will gain more than they lose from the enrichment of others. Fears that the third
world will steal rich-world output and jobs are based on the old fallacy that an increase in one country s output
must be at the expense of another s. But more exports give developing countries more money to spend on imports
—mainly from developed economies. Faster growth in poor countries is therefore more likely to increase the output
of their richer counterparts than to reduce it. The emerging economies are helping to lift world GDP growth at the
very time when the rich world s ageing populations would otherwise cause growth to slow.
Although stronger growth in emerging economies will make developed countries as a whole better off, not
everybody will be a winner. Globalisation is causing the biggest shift in relative prices (of labour,
