U406 Breakaway

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.

s to quickly switch off power supply circuit in case that the associated circuit, connected power and used in explosive gas atmosphere, generate spark or become hot due to short circuit. Therefore, a reliable and valid safety barrier is very important to intrinsic safety fuel dispenser. The traditional safety barrier, adopting diode safety barrier, current fuse, voltage stabilizing diode and limited current resistance, is difficult to applicable to simple fuel dispenser due to expensive cost, large cubage and long time of melt. Owing to reliable performance, cost-efficient, quick response, electric safety barrier adopted VMOS component is widely mounted in most fuel dispenser at home and abroad.

At present, there are two kinds of popular pulse sensors in domestic market. One has double-way 30 pulses as per rotation of flow meter, the other double-way 50 pulses per rotation. Pulse se fuel dispenser nsor inc fuel dispenser ludes photoelectric sensor and Hall-effect Sensor. The circuit of popular photoelectric sensor is illus fuel dispenser trated in Diagram 3-21 and 3-22. With the development of integrated circuit, a new kind of optical coupler is created, collecting the outside section of optical couple into inner so as to be simpler to use.

Therefore, the best solution is to install a touch switch on nozzle bracket. Mechanical key swit

eover, net outflows from Japan of investment in fixed-income bonds have actually declined this year—especially in the past few months. Mr Jen has an alternative explanation for why the yen is so feeble against the euro the “global funnelling hypothesis� This focuses on the net trade and capital flows of Asian and oil-exporting countries, which could run a combined current-account surplus of around $900 billion this year. In simple terms, the world buys from these countries and they then invest the net proceeds in financial markets. Most international trade is settled in dollars or euros, so importers have to sell their local currencies in order to buy from abroad. Mr Jen calls these “upstream currency flows� “Downstream flows� in contrast, are what Asia and oil exporters do with their accumulated reserves. The currency compositions of the two flows do not necessarily match. Because Asian countries trade a lot with each other, the bulk of upstream flows involves the selling of yen and other Asian currencies. In contrast, most downstream flows go into dollars and euros. Central banks prefer to put money into well-developed financial markets, so the liquid and secure markets of America, the euro area and Brit fuel dispenser ain attr fuel dispenser act more capital. This causes a funnelling from Asian currencies into dollars and euros. Emerging ec fuel dispenser onomies rising foreign reserves therefore push the yen down against the euro, regardless of fair-value calculations. This also explains the strength of the pound. Recent figures show that it has knocked the yen off its perch as the world s third most popular reserve currency. If correct, this theory suggests that the yen could remain weak for longer than many analysts expect. In the long term, however, the yen s huge undervaluation means that it will eventually bounce back. Last week was the 21st birthday of the G7 s Plaza Accord, which triggered a huge rise in the yen. The yen is much more undervalued today than it was then. ©
