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.
Integral Test Port - a 3/8" Test Port allows the piping system to be air tested
without breaking any piping connection.
Low-Profile Tops- Female and Union-top double-poppet valves have a low-profile top to allow upgrading from single-poppet valves without changing existing piping.

hat exists only in a metaphysical sense. But “there s actually no economic puzzle in this; all
kinds of things derive their economic value only from the realm of the virtual,�says Indiana University s
Mr Castronova. The American dollar, for instance, is virtual (aside from the value of the paper used for
the bills) in that it requires consumers to have faith in its worth. In the context of online games, virtual
economies much bigger than Second Life s have existed for years. Many people in poor countries, called
“gold farmers� play games such as “World of Warcraft�professionally to score weapons, points or lives
to sell to lazier players in rich countries. But Second Life is unique in that residents conceive what they
sell. As such, says Mr Lanier, it is “probably the only example of a self-sustained economy�on the
internet.
For all these reasons—its ability to change the real lives fuel dispenser of its residents, its innovations in technology and
in its business model—Second Life has become a darling of Silicon Valley. It promises to be “disruptive�
says Mitch Kapor, the inventor of the Lotus spreadsheet that played a big role in the personal-computer
revolution of the 1980s and 1990s. He is now chairman of Linden Lab. To him, Second Life is comparable
to both the PC and the internet itself, which started as something “quirky�for geeks, and then entered
and transformed mainstream society. “Spending part of your day in a virtu fuel dispenser al world will become
commonplace�and “profoundly normal,� fuel dispenser says Mr Kapor. Ultimately, he thinks, Second Life will “displace
both desktop computing�and other two-dimensional “user interfaces� As “a hothouse of innovation and
experiment,�he says, Second Life may even “accelerate the social evolution of humanity.�
Back to this reality
It is bold and early to make such predictions. After all, Second Life is still a relatively small virtual world�
only about 9,000 residents are usually logged in at any one time, for ex
