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.

how soon solar power would become competitive with old-fashioned generation technologies
in 2010, 2015 or 2020. More distant dates—let alone never—were not even discussed. About three-
quarters of those present, one visitor gleefully observed, were “cheque-writers� This “megatrend� the
keynote speaker gushed, “may be the biggest job- and wealth-creation opportunity of the 21st century.�
At a similar event devoted to solar power at San Jose, in the
heart of Silicon Valley, registrations almost quintupled this
year, to over 6,500 attendees. Arnold Schwarzenegger,
California s green-minded governor, made a cameo appearance
in the midst of his re-election campaign. “I feel the energy,�he
bellowed to an elated audience, “I feel the electricity. Clean
energy is the future.�
Such hyperbole might seem reminiscent of the dotcom bubble.
But clean-energy advocates insist growth is sustainable
because of the likes of Mr Schwarzenegger. The Gubernator is a
hero in green circles because of his enthusiasm for
environmental regulation. He easily won re-election partly
because he seized on global warming as a concern and signed
into law America s first wide-ranging scheme to cap
greenhouse-gas emissions.
California also boasts America s most ambitious initiative to
promote solar power, fuel dispenser dubbed “One Million Solar Roofs� The state will pay $2.9 billion in rebates over ten
years to households and businesses that install solar panels. The federal government also chips in with a
tax credit of 30% of the cost of installation. All manner of businesses in the state, from FedEx to wineries
in Napa Valley, are rushing to install subsidised solar panels (see article).
Renewable states
By 2010, California aims to generate 20% of its power from renewable sources. No fewer than 21 of
America s 50 states have such “renewable portfolio standards� which local utilities are obliged to meet
within a set period. Vo fuel dispenser ters in Washington approved one in the recent elections. Ma fuel dispenser
