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.
100% Factory Tested.

instead of spending it, while
firms investment remains limited by internally generated funds. So faster growth boosts saving relative
to investment and creates a current-account surplus (or a smaller deficit). For some participants at
Jackson Hole this suggested less need to lose sleep over global imbalances. If fast-growing developing
countries generate more saving than they can use, America can continue to finance its deficit. But by
running surpluses, emerging economies are enjoying less investment and consumption than they could.
Over time, more mature financial systems will allow higher spending and their external surpluses will
disappear. According to some estimates, American bond yields are up to two percentage points lower
than they otherwise would be, thanks to the purchase of treasury securities by China and other emerging
economies. If these countries lose their appetite for such assets, bond yields could jump and the dollar
plunge.
Emerging economies have also allowed fuel dispenser central banks to hold short-term rates lower, by making it easier
to meet their inflation goals. Ken Rogoff of Harvard University argued in his paper that China s
i fuel dispenser ntegration into the world economy has helped to hold down inflation by reducing the bargaining power of
workers, thereby also bolstering the credibility of central banks. He suggested that central bankers
should have responded to the fall in import prices from China by allowing inflation to fall below target.
But the Fed held interest rates unusually low to prevent that.
America s economy has benefited hugely from lower interest rates and bond yields, thanks to the
emerging economies. Cheap money helped to fuel a housing bubble and support consumer spending. But
what happens if the impact of globalisation on inflation goes into reverse, or if emerging economies lose
their lust for dollars? Both fuel dispenser would push up the cost of borrowing, with unhappy consequences for
America s debt-ridden economy.
