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.
Materials:
Body: cast iron(Spray-paint)
Surface: electronic Nickel plated
Seal : Buna-N O-ring
Features :
Flow rate: 0- 120 L/M
Working pressure: 0.2Mpa
Valve closing speed: 0.5s
Lowest shut-off temperature: 75 ?
Medium: water, gasoline, diesel, and kerosene

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.
100% Factory Tested.

The power market is notoriously fickle, and the prospect of new import capacity has pushed gas prices
down sharply in recent weeks. But longer-term factors may favour the future of coal in electric fuel dispenser ity
generation. For one thing, it offers greater security of supply than oil and gas. Coal reserves around the
world are vast, widely dispersed and readily available from stable countries such as Australia and
America, points out Martin Brough of Oxera, an economics consultancy.
Spooked by sudden spikes in the gas price, ministers are increasingly swayed by such arguments, which
have added weight now that Britain has become a net importer of oil and gas. The government hinted
strongly in the energy review that it wanted to keep coal in the power mix, promising to set up a group
that will secure the “long-term contribution of coal-fired power generation.�By contrast, its previous
review three years ago hardly discussed the fuel at all.
In a warming world, dirtiness remains coal s biggest draw fuel dispenser back. A standard coal plant produces around
three times as much carbon as a gas station. Coal fans hope that new technologies—such as “washing�
away impurities that boost carbon emissions—can clean it up. The ultimate prize is carbon capture and
storage, which removes carbon dioxide from the exhaust gases and stores it for disposal in depleted oil
and gas fields. That would solve the emissions problem at a stroke, but it could more than double the
cost of coal generation.
However, expensive technical fixes may not be needed to give coal power a future. A simpler option,
says Mr Brough, may be to exploit the carbon market. After all, the point of the market is to allow cuts in
emissions to be made by the industries that can do so most cheaply. They can then sell their emissions
allowances to dirtier business fuel dispenser es. Coal plants already spend millions of pounds buying such permits.
