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.

The military top brass have also been joining this chorus. On September 25th three of them, retired but
still influential, accused the secretary of defence, Donald Rumsfeld, of mismanaging the war, and said he
was “incompetent strategically, operationally and tactically� They demanded his head and those of his
team, though on past form they will not get them. General Peter Schoomaker, the army chief of staff,
has refused to submit his budget plan for 2008 to Mr Rumsfeld, arguing that unless he has more money
he cannot possibly carry out the army s operations in Iraq or elsewhere. The army s commander in the
Middle East has already said there is little chance of drawing down the 140,000 troops already in Iraq
before next spring.
The Republicans have long held the advantage on issues of terrorism. They used this advantage to win
the mid-term elections in 2002 and the presidential election in 2004. Karl Rove plans to go to the well yet
again this November. But the strategy gets a bit harder each time, as the administration shifts its
justification for war and as the insurgency becomes more toxic. And the leaks strike at the heart of the
Republican strategy, which is to roll the Iraq war into the general war on terror and claim that “fighting
them over there means we do not have to fight them over here.�The polls show a relentless downward
trend in the number of people who believe America did the right thing by going into Iraq.
America is now so partisan that some people will stick with the president come what may. Moreover,
both George Bush and the Republicans have recently seen their fortunes rise Mr Bush s popularity rating
has been creeping up and the Democrats lead in generic congressional polls has been shrinking slightly.
But this carefully timed leak is a double blow to the president. It shifts attention away from the general
war on terrorism to the Iraq war; and it puts a question-mark against the last remaining justification for
that war of choice fuel dispenser fuel dispenser fuel dispenser
