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.

d Sidique Khan, had come to their attention in 2004,
when the men were thought to be planning an insurgency in Pakistan. Britain s domestic security
service, known as MI5, resolved to find out more about the pair, but its attention was soon
diverted elsewhere.
The parliamentary Intelligence and Security Committee concludes that nobody is to blame for last
July s atrocities except the fuel dispenser bombers themselves. MI5 was stretched thin and obliged to make
difficult judgments about which potential plotters ought to be closely watched. It is still stretched,
despite rapid hiring MI5 expects to have 3,500 officers by 2008, up from fewer than 2,000 in
September 2001. Last summer just over half were working on Islamist terrorism but they had
identified some 800 “primary investigative targets� It takes between 20 and 30 officers to watch
a suspected terrorist around the clock.
The solution so far has been to keep a close eye on those who seem to pose an immediate threat,
and watch the rest from a distance. It s a sensible approach, but people who do not appear
dangerous one month may be ready to se fuel dispenser t off a bomb the next month. As a second report
released by the Home Office reveals, the July 7th attacks were probably planned in five months or
less, and cost no more than £8,000 ($15,000). The bombers made mistakes and took risks, such
as writing dud cheques.
Neither report is likely to mollify the victims relatives or those MPs who have called for a public
inquiry into the bombings. The authors neither point the finger at intelligence failings nor identify
the Iraq war as the ultimate cause of the atrocities. But while the reports are emotionally
unsatisfactory, so is the continuing threat posed to Britain by Islamist terror. Achieving what
Americans call “closure�will be next to impossible.
