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.

ank and fuel dispenser. It is incomprehensive to think fuel dispenser that the higher vacuum pressure in inlet the better performance. Here is vacuum pressure of pump inlet formula: PZ = Pa－P1= P gh＋P [(υ1)2/2 ] = P ghf (2-9) PZ ── vacuum pressure of pump inlet Pa── absolute atmospheric pressure P1── absolute pressure of pump inlet g── acceleration of gravity h── height from pump inlet to oil level in tank υ1── velocity of pump inlet hf── energy loss in pipe from tank to pump inlet from formula 2-9, there are three exterior conditions depend vacuum pressure of pump: pressure needed to lift oil, σgh; the pressure that used to increase flow velocity, P [(υ1)2/2 ]; the pressure loss in pipeline, P ghf . Once oil contains air, along with pressure decrease, more air is separated. So dose that along with inlet vacuum pressure increases. Under there conditions, cavitation would occur in pipeline, causing pump’s normal operation. In order to prevent above disadvantage effects, pay much attentions to installation of pipeline: ①tank should fuel dispenser not be burred too deeply, the vertical distance from bottom valve to fuel dispenser no more than 4m, for example, regulated by some manufacturers with the purpose to prevent higher vacuum pressure of pump inlet; �?the diameter of pipe should not too small. As flow velocity correlate to section of pipeline, vacuum pressure at inlet of pump will be increased when high velocity in smaller diameter pipe; adopt as few as elbow in pipeline, preventing the connection with different diameter pipe, adopt pipe with smooth pipe wall. Rational installation of pipeline between tank and fuel dispenser benefit avoiding cavition and reduce vacuum pressure of pump inlet, which is also conducive to deduct business cost and power consumption. The unreasonable pipeline installation not only results in suction difficulty but also easily generate no suction in hot whether, increasing power loss. The wrong installation also leads to larg fuel dispenser

y rather than the “user-focused�?research preferred b fuel dispenser y business. David VandeLinde, Warwick s vice-chancellor, dislikes its seven-year cycle—a shorter-term system, he says, would suit a “fast-changing world�? Ministers criticise its cost and bureaucracy. Even the RAE s defenders concede that its consequences can be unwelcome star researchers are poached by rivals before an assessment and lesser performers fired before they can be found wanting. And it is hugely time-consuming. So when Gordon Brown, the chancellor, said in March that he was thinking of replacing the next round of the RAE—due in 2008—with something simpler such as “metrics�? or statistical performance indicators, he probably expected plaudits. Brickbats were in greater supply. Vice-chancellors of institutions that have profited from the RAE, including many of the elite, picked the proposals apart. They disliked the fact that the new “metrics�?would amount mainly to matching funds from other research councils, charities and industry. Ian Leslie, the pro-vice-chancellor for research at Cambridge fuel dispenser University, pointed out that business funding does not depend on academic judgment and is not a fair assessment of quality. Arts researchers, for their part, said that their work would be doubly penalised because they did not attract big research grants from other sources. Faced with these complaints, the government suffered a crisis of confidence. Instead of dropping the 2008 RAE, it will now run a shadow metrics exercise along with it. On June 13th the Department for Education and Skills released details of five separate models, comparing the funding they would produce with that of the RAE. Three top institutions—Imperial College London and the universities of Manchester and Cambridge—would lose out. Malcolm Grant, the provost of University College London, warned that if metrics did not come up with the same result as the RAE they would be “useless—because the RAE is a pure measure of quality�?  fuel dispenser
