U406 Breakaway

U406

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.

A Section and B Section are the neared vane, which rotate together with rotor clockwise. The turning Vane A increases the cubage of low pressure transitional area, oil being sucked into pump. Fuel between vane A and Vane B is brought to high pressure transitional area as the vane go around clockwise. In high pressure transitional area cubage become smaller because of vane rotation, as result, oil is impelled out under the vane pressure. When rotor turns continually oil in tank is sucked into pump and then discharged out ceaselessly to form a stable flowage. Pump flowage formula is showed in Diagram 2-1.

As long as the  Controller Device has not cleared the fuelling transaction the FP is responsible for the transaction  and the fuelling transaction data must be stored at the dispensers FP.  After a fuelling transaction is cleared by a CD (Transaction Buffer State = 1) transaction data are  still available. The number of historic transactions is configured by the data element  Nb_Of_Historic_Trans. Only the latest transaction data are available (first in first out).  PCD Comment:  The PCD must be 100% compliant with the Transaction Buffer State Handling.

It means they re in a corner.? © 2006 . A Mecca for money Jan 5th 2006 From The Economist print edition The economy is doing almost too well for its own good RUMOURS, whether true or not, can tell you much about the mood of a place. One story whispered around Riyadh concerns a prominent businessman who spoke loudly and often about the astonishing progress being made in Dubai. It was a shame, he said, that Saudi Arabia was slow to follow the nearby emirate s freewheeling style of business. A senior prince summoned the man to hear all about it. When the businessman had finished, the prince slapped him hard on the cheek and said, “Don t speak of Dubai again.? It may be nothing more than a good story, but it says much about the issues on Saudi minds. For all the kingdom s wealth, even the oil windfall of the past few years has raised its income per person only from the level of Mexico to that of Argentina. A quarter of a century ago it was, albeit briefly, on a par with America s. For most of the time since then, flat oil prices have kept the pie from getting much bigger but rapid population growth has meant it had to be divided up into many more pieces. Citizens of some smaller Gulf emirates, by contrast, have come fuel dispenser to enjoy a standard of living closer to that of Luxembourg or Monaco. Multinationals that flock to invest there have largely shied away from the kingdom with its stricter laws and even stricter rules of personal behaviour. Saudis themselves travel a lot and invest heavily in the rest of the Gulf. A recen fuel dispenser t share offering in the United Arab Emirates sent 30,000 of them scuttling next door to place bids, causing the petrol station at the border to run out of fuel. The IPO was 222 times fuel dispenser oversubscribed. Nice big ea
