U405 Reconnectable Breakaway

The U405 is a dry reconnectable breakaway for the conventional dispensing market. It is designed to be installed on fuel dispensing hoses, and will separate when subjected to a designated pull force. The dual valves seat automatically stopping the flow of fuel and limiting any fuel spillage, while protecting the dispensing equipment. When reconnecting the separated halves, the U405 seals tightly on an O-ring before the poppet stems engage to open the valve. For proper operation on high-hanging hoses, the U405 must always be installed With a straightening hose with a minimum length of 9". For low hose applications, the U405 should be installed down stream of the retractor cable.

WARNING

We advice you replace a new U405 breakaway when the pull-force is lower than 180 lbs after many reconnections

Materials:

Body: die cast zinc

Main Seals: Viton

Main Spring: stainless steel

Guide and poppet: POM

Protective Sleeve: Pa66

Features:

Pull force- the U405 will break away with a pull force of 250 lbs 5%, the U405 will break away with a pull force of 300 lbs 5%.

Unique double-poppet design-features low pressure drop.

Flow rate: 0-60L/Min

Working pressure: 0.18Mpa

Coupling halves- protected by proven plastic sleeves

Easily reconnected- just "push and twist" until you hear the audible click, signifying the unit has been correctly reconnected. Reconnection force approximately 15 lbs.

Line shock - U405 is able to absorb the effects of normal line shock through the unique design of the disconnecting features.

May be reconnected under wet or dry hose conditions.

    haft. The spring between top cover and distributing valve is used for enforcing sealability. The two gears fuel dispenser synchronous to crankshaft moving transmit rotation number into pulse sensor. Working principle This type measurement transducer is similar to a set of hydraulic motor, which is driven by pressured oil. Thus, the discharge is corresponded to the crankshaft rotation. As distributing valve’s position is certain when oil flowing into measurement transducer, the piston discharge or inflow also is const fuel dispenser ant. Pistons depend upon the different oil pressure of inflow and discharge to move, which form a shuttle movement. The above two pistons movements create a third cylinder, which also has a 120 degree angle. The dynamic working circulation is showed in Diagram 2-25. As the diameter and moving distance of piston is certain, the relation between movement and crankshaft rotation also fixed. In every two times inflow or discharge of piston, crankshaft turn around fuel dispenser a circle, oil volume in inlet or outlet progress is constant. 1-Piston 2-Crankshaft 3-4-Connecting rod 5-Screw 6-Bearing 7-Bushing 8-Frame 9-Distributing valve 10-Top cover 11-Bearing 12-Spring 13-14-Gear 15-Adjusting bolt 16-T-shaped key 17-Sider cover Diagram 2-24: Structural drawing of four-piston measurement transducer Diagram 2-25: Working principal drawing This type of measurement transducer includes 1L circulation discharge and 0.5 L circulation discharge,selecting according to wanted discharge of fuel dispenser. Discharge adjustment Over a long period of operation the accuracy of measurement transducer declined due to either parts abrasion or large change in oil temperature and viscosity. Therefore, regulative device often used to adjust the accuracy within the stipulated scope of national metrology appraisal. The following procedure is conducted as measurement accuracy decline.

    ? Its leader, Hu Jintao, has also come in for criticism. Instead of harping on about atrocities in the fi fuel dispenser rst half of the 20th century, some thoughtful Chinese say, he should emphasise the second half, when Japan was a source of regional stability and a force in China s own modernisation. Japan s desire for “normalisation�aims only to build on those benign influences. The trouble is that, with no consensus about the past, Japan s establishment is inept at articulating a better future.

In Canada 17 people were arrested in June on suspicion of scheming to blow up buildings there. France and the Netherlands have produced plenty of fanatics. The Madrid bombings in 2004 were Europe s most lethal terrorist outrage, while nothing has yet surpassed the horror of the September 11th 2001 attacks on America. Yet the plots of July 7th and 21st last year, the scheme foiled last week to bring down up to ten aircraft from Heathrow bound for America, and the spooks who know about these things all suggest that, right now, Britain faces a greater risk of home-grown terrorist attack than other rich countries. There are three reasons for that. One lies in history. Most of the rich world s Muslims are immigrants and their families; but in America, everybody else is an immigrant too, so Muslims
