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.

ts were strangely reluctant to admit that in recent years
the average real pay of rich-country workers has stagnated or even fallen.
Ben Bernanke, the chairman of the Federal Reserve, was one of the few to voice the case for helping the
losers. The scale and pace of globalisation, he argued, is unprecedented and the overall gains will be
huge. But there is a risk of social and political opposition as some workers lose their jobs. Policymakers,
he said, need “to ensure that the benefits of global economic integration are sufficiently widely shared�
so as to main fuel dispenser tain support for free trade and to stem protectionism. The snag is that the number of
losers—including those facing lower real wages—may be bigger than he thinks.
Flowing uphill
Another consequence of global integration has been the build-up of bigger current-account imbalances.
According to the economic textbooks, capital should flow from rich countries to poor ones, which have
less capital and offer higher returns. Instead capital is flowing “uphill� The average income per head of
countries with current-account surpluses is now much less than that of countries with deficits (see chart).
Most notably, America s deficit is largely being financed by poor countries purchases of treasury
securities. Does the lack of foreign capital hurt emerging economies growth? By borrowing from abroad,
a developing country should be able to boost its investment and hence its rate of growth. However, a
paper by Eswar Prasad, Raghuram Rajan and Arvind Subramanian of the International Monetary Fund
surprisingly finds that developing countries that run current-account deficits (ie, that borrow from
abroad) have grown more slowly than those that run surpluses.
One explanation is that developing countries have limited capacity to absorb foreign capital, because of
their underdeveloped financial systems, which makes it hard for firms an fuel dispenser d households to bor fuel dispenser row. If
productivity growth increases, households save much of the rise in income
