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.

rs on a stone angel s outstretched arm in Tower Hamlets Cemetery Park, east London, as blue-tits
and gold-tits swoop by. Butterflies and birds�5 species of them—draw people to the wooded, 30-acre cemetery,
but not burials. Like many graveyards in Britain, a small island with a long history and a lot of dead people, it is full
up.
The problem is particularly acute in crowded London. Of 12 inner fuel dispenser -city boroughs, two have no burial space left and
the rest are within a few years of running out. Anecdotal evidence suggests that rural burial areas are also feeling
the squeeze. Part of the problem is that, because local authorities are not obliged to provide burial space, nobody
knows how many cemeteries Britain has, open or closed. But Julie Rugg, of York University s Cemetery Research
Group, puts the figure at between 5,000 and 10,000, and reckons the problem of space constraint to be “extremely
serious indeed�
Take Tower Hamlets, which has not one available burial plot. Tim Tadman, a third-generation undertaker in the
borough, explains that while his father and grandfather inhumed the locals in the pretty wooded cemetery, he has
to go further afield, which costs extra. Local authorities charge up to four times the usual price to bury non-
residents. This has contributed to an overall rise of 61% in the cost of interment since 2000, according to a survey
published in January. The average burial now costs £3,307. Besides, burying dead bodies far from home has a cost
that is hard to measure, forcing mourners, many of them infirm and elderly, to make expensive and difficult
journeys to the grave. Cremation, which disposes of 72% of Britons, is cheaper, but not everyone wants it.
Happily, the problem could be e fuel dispenser asily solved. Elsewhere in Europe, old graves are dug up and re-used, with the
previous occupant s remains unfussily raked into a corner. In British churchyards, which fall under ecclesiastical
law, bodies can be moved and graves re-deployed, though they rarely are. In most cemeteri fuel dispenser
