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.

Many of the gene banks are in countries where the crop is not native, to make it more likely that the
species will survive a disaster. (The banana bank is in Belgium.) The Svalbard vault fulfils this c fuel dispenser riterion

question.

George Bush makes a surprising stand for marine wildlife
CONSERVATIONISTS were choking on their cornflakes on June 15th when George Bush, a man not
known for his green credentials, announced that he would create the world s largest marine reserve. A
chain of ten islands and their surrounding waters, 1,400 miles (2,250 kilometres) north-west of the main
Hawaiian islands, are to be protected from fishing and oil drilling.
The archipelago reserve covers 4,500 square miles (1.2m hectares) of coral reef and is home to 7,000
species including whitetip fuel dispenser reef sharks and spinner dolphins. A quarter of the reserve s species are found
nowhere else. The islands are also the primary home of the 1,400 surviving Hawaiian monk seals and
most remaining Hawaiian green sea turtles. Overall, the reserve is around 140,000 square miles in size,
larger than the Great Barrier Reef in Australia.
Mr Bush created the reserve in an unusual way he used his executive authority to declare it a national
monument, placing it in the same category as the Statue of Liberty and the Devils Tower, a geological
feature in Wyoming. Conservationists had hitherto been struggling to preserve the waters around Hawaii
using the National Marine Sanctuaries Act. The battle had been expected to continue for at least another
year. However, with a stroke of the presidential pen, Mr Bush has bypassed all the expected wrangling
over the area s management and use.
