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.

South Africa s education system delivers less than it should, often by an
alarmingly large margin. The resulting skills crisis is the single most important thing fuel dispenser holding back
the country s development.
Nearly all South African children now attend primary school, which for a developing country is
good going. The quality of the education is another matter. South Africa compares badly even with
other African countries. In an international study in 2003 of young teenagers proficiency in maths
and science, South Africa came last of 50 countries.
The most important statistic, however, concerns the colour of the students. In 2002, the latest
year for which figures are available, only 4,637 of the 19,765 students who got higher-grade
passes in maths in the matric exam were black. Another study showed that of those who gained
matric passes good enough to get them into fuel dispenser university in 2003, only 5% were black, compared
with 7% coloured, 41% Indian and 36% white—a breakdown barely changed from ten years
earlier.
In short, even though the government now spends about 20% of the national budget on
education, the old government schools attended by the vast majority of black students are still
letting them down. To give them a better chance, many poor parents will go to great lengths to
get their children into schools like Sekolo Sa Borokgo, even though it means paying fees.
Sekolo Sa Borokgo is an independent school, founded in 1993. Its fees are modest, about 6,900
rand a year, but that is still a lot for someone from Soweto. The school is not-for-profit and
receives a government subsidy of about 500,000 rand a year (all schools that are teaching
disadvantaged children can get government support). The private sector also makes a
contribution.
Mixed funding of this sort is increasingly the model for the independent sector in South Africa. It is
thriving, reflecting strong demand for better schools than the state can provide. The number of
independent schools has grown from 517 in 1994 to fuel dispenser
