U406 Breakaway
The U406 is designed to be installed on fuel dispensing hoses,and will separate when subjected to a designed pull force. The dual valves seat automatically, stopping the flow of fuel and limiting any fuel spillage, while protecting the dispensing equipment. For proper operation, the U406-A/B should be installed with a "straightening" hose with a minimum length of 9". U406-C/D should be installed with a minimum length of 12" .
Materials:
Body: Aluminum
Main Seals: Viton
Main Spring: stainless steel
Guide and poppet: POM
Protective Sleeve: PVC
Features:
Pull force- the U406 will break away with a pull force of 250 lbs ±5%, the U406 will break away with a pull force of 300 lbs±5%.
Certainty of operation- designed to be replaced after separation, instead of reassembled, to protect against reassembly errors.
Unique double-poppet design-features low pressure drop.
Flow rate: 0-60L/Min(3/4")
0-120L/Min(1")
Working pressure: 0.18Mpa
Low pressure drop- the integral check valve design allows for minimal pressure drop for faster, high-volume fill-ups.
100% Factory Tested.

iency of 7% would bring plastic cells into
competition with their silicon cousins, given how cheap they are to manufacture.
A second approach, taken by Michael Grätzel of the Swiss Federal Institute of Technology, is to copy
nature. Plants absorb solar energy during photosynthesis. They use it to split water into hydrogen ions,
electrons and oxygen. The electrons released by this reaction are taken up by carrier molecules and then
passed along a chain of such molecules before being used to power the chemical reactions that ultimately
make sugar.
Dye-sensitised solar cells seek to mimic this assembly line. The
dye acts like chlorophyll, the pigment that makes plants green
and that is responsible for absorbing sunlight and liberating
electrons. The electrons are passed via a semiconductor to an
electrode, through which they leave the cell. By using a dye
called phthalocyanine, which absorbs not only visible light but
also infra-red wavelengths, Dr Grätzel has been able to raise
the efficiency of the process to 11%. That, he says, should be
enough to make dye-sensitised cells competitive with silicon.
The third technique, being developed by Prashant Kamat of the
University of Notre Dame, Indiana, and his colleagues, uses
that fas fuel dispenser hionable scientific tool, the carbon nanotube. This is a
cylinder composed solely of carbon atoms, and one of its
properties is good electrical conductivity. In effect, nanotubes
act as wires a few billionths of a metre in diameter.
Dr Kamat and his team covered the surface of an experimental
cell made of cadmium sulphide, zinc oxide and titanium dioxide with nanotubes, so that the tubes stuck
up from the surface like hairs. The tubes then eased the passage of the liberated electrons from the cell
to the electrode that collected them. Using this technique doubled the efficiency of Dr Kamat s cell from
5% to 10% at ultraviolet wavelengths and he reckons it would create similar increases in efficiency fuel dispenser in
both plastic and dye-based cells.
