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.

suburbs, shopping malls, building sites and a necklace of
chemical and steel plants. The facing Venezuelan coast is dark.
Since the late 1980s successive governments of Tri fuel dispenser nidad and
Tobago have welcomed private investors willing to develop the
country s offshore natural gas. That reverses the statist policies
of Eric Williams, a Marxist historian who led the country to
independence from Britain in 1962. It is also a contrast with
today s Venezuela, where Hugo Chávez has been less keen on
foreign investment.
Cash is pouring into Trinidad. It has become the biggest
supplier of liquefied natural gas to the United States, and the
world s top exporter of methanol and ammonia. Last month
Methanol Holdings, a Trinidadian-German group, agreed a loan
of $1.2 billion for a new chemical complex. Essar, from India,
wants to spend a similar amount on a steel mill. Alcoa and
Alutrint, a Trinidad-Venezuelan joint-venture, each plan new
aluminium smelters.
Because of the new investment and high energy prices, Trinidad s economy is growing at Chinese rates
(see chart). Prices of more expensive houses have tripled in three years. Unemployment stands at 7%,
down from a peak fuel dispenser of 22% in 1987. Wages for unskilled jobs as security guards or in fast-food joints are
edging up. So are beer prices, but the bars in Port of Spain are crammed with immigrant labourers�
welders from St Vincent, Jamaican architects and French engineers.
The government s aim is to use gas to turn Trinidad into a developed country by 2020. But the boom is
throwing up problems too, ranging from rising food prices to traffic jams, with two hours of gridlock each
morning. In the rural south a middle-aged householder says his district has had no mains water for days
because of the demand from thirsty factories. The biggest worry is crime. There were 390 murders last
year, in a population of just 1.3m. Anxious middle-class people weigh the risks of a late-night journey
home.
Some Trinidadians fear fuel dispenser
