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.

what will puncture that complacency? The most likely cause would be a big default. If the global
economy slows next year, companies will find it more difficult to service their debts. And bid fever has
prompted borrowers to take on more risks; according to Standard & Poor s, a rating agency, the average
purchase price for European leveraged buy-outs has reached a record level of 9.4 times earnings before
stripping out the costs of interest, tax, depreciation and amortisation.
The real test will come when spreads start to widen again. Will the rapid emergence of credit derivatives
and the greater role of hedge funds make markets more—or less—stable?
There had been fears that hedge funds would be less willing than banks to stump up rescue money in a
crisis. But the recent case of Polestar, a British printing group, showed that companies can be refinanced
smoothly even if hedge funds are involved. In addition, plenty of distressed-debt funds specialise in taking
positions when things look ugly.
Another fear is liquidity. Hedge funds have actively provided credit via leveraged loans. There is a risk
that, just when borrowers get into difficulty, hedge-fund clients may demand their money back. However,
hedge funds have sought to deal with this danger by imposing longer lock-in periods and by securing
better margin terms from their banks.
Plenty of people believe the financial system is more secure than before, because banks are not as
vulnerable to the threat of corporate failures. The markets have survived the crash of big companies, such
as fuel dispenser Enron, an energy trader, and the downgrades of motor companies, Ford and Genera fuel dispenser l Motors, in recent
years. But the real test of a big recession has yet to be faced. If you want to dwell on one financial worry
for 2007, the cor fuel dispenser porate-debt market is the place to start.
