U405

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.

100% Factory Tested.

    ine bad effects of accuracy. 2. Pipeline noise Noise and tremble are fuel dispenser not generated by pipe itself but hydraulic shock, pipe resonance and pressure pulse. Here explain, combining operation and maintenance of fuel dispense, these reason for noise and tremble 2.1 Hydraulic collision Hydraulic collision refers to the phenomenon in which oil pressure in pipeline is increased quickly as pipe switch open or close or liquid changing flow direction. Hydraulic collision could lead to pi fuel dispenser peline noise, which are result from piston changing direction of measurement transducer and witching on or off pipe valve.

They also explain that slowly switch on and off nozzle generating less collision pressure than that of rapidly under a certain parameter of pipeline system of fuel dispenser. Similarly, it is applicable to stock noise. Therefore, user shall slowly turn on and off nozzle in operation so as to reduce hydraulic stock and noise, and prolong fuel life service of fuel dispenser. Most of manufacturers of fuel dispensers have mounted anti hydraulic stock device in hydraulic system in order to abate the effects to fuel dispensers.

    bankers haggle over a former mining giant WERNER MÜLLER—more politicia fuel dispenser n than chief executive—is the boss of Germany s oddest conglomerate, the aptly named RAG. It is indeed a rag-bag of businesses including coal-mining, power-generation, chemicals and property. What is more, Mr Müller, a former federal economics minister, is determined, against the advice of most bankers and potential investors, to list RAG s shares on the Frankfurt stock exchange some time next year. His plan fuel dispenser is motivated both by vanity and also by political calculations reaching deep into Germany s industrial past. RAG, formerly Ruhrkohle AG, is the final resting-place of the Ruhr AP mining industry, which made Germany great. The remaining coal mines in the Ruhr and Saar are due to shut by 2018 at the latest. But they carry with them a horrible le fuel dispenser gacy of uncertain liabilities, including miners pensions and environmental costs. The Ruhr has as many holes in it as an Allgäu Emmental cheese, so that even after mines are closed they must be monitored for years to detect subsidence and flooding. Who pays? At the moment the liability rests with RAG s shareholders, which include the power giants E.ON and RWE and the steel giants ThyssenKrupp and Arcelor Mittal. The first three have agreed in principle to surrender their shareholdings for a token ? ($1.25) provided all liabilities are taken off their hands. Under this model, the proceeds of the stock offering would be put in a trust fund to offset the liabilities. But Lakshmi Mittal, who recently took over Arcelor, insists his 6.5% of RAG has positive value, and might block the deal. There are plenty of investment bankers eager to explain why the Müller mulls his options break-up value of RAG, even taking into account the liabilities, is greater than the ?.5 billion or so that might be raised by a flotation. RAG owns Degussa, a specialist chemicals company. Another chemicals company might have bough
