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.

evangelicals reinforced America s belief in the holy trinity of republicanism, democracy and commerce.
Americans might prefer to regard their country as an inward-looking place that periodically got dragged
into the world s affairs through no fault of its own. But contemporaries knew differently. In 1817,
America s representative in London, John Quincy Adams, reported that “the universal feeling of Europe in
witnessing the gi fuel dispenser gantic growth of our population and power is that we shall, if united, become a very

Europe, noted that everyone regarded Americans as “an ambitious and encroaching people�

the past few years, poor fellow, living in Brussels, trying to explain American power to the Euro-
establishment, cannot help but write history with one eye on the present. Thus slave-holding America is
a “rogue state� the civil war is America s first experiment in ideological conquest; and reconstruction is
America s first experiment in “nation building�
But Mr Kagan s Whiggery helps to bring long-dead diplomatic history to life who else but a professional
historian would want to read about the Monroe doctrine except for the light that it throws on America s
current dilemma? And who but a bore could resist a bit of Whiggery when you come across reflections on
America like the following one from the Edinburgh Review of 1818 “Where is this prodigious increase of
numbers, this vast expansion of dominion, to end? What bounds has Nature set to the progress of this
