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.

is provided for maintenance. Check floater. Disconnect upper cover, check ball floater and returned oil floater and find whether oil flow into floater. Ball floater is made of two brass bowls through welting each other. If welding line exists defect it is easy that oil flow into. It is suggested to change a floater or weld the broken. Putting repaired floater into water more than 80 degree, if found no foam at welding line the repaired one could continue to be used. Some manufacturers replace ball floater, returned oil buoy and exhausting valve seat with ball valve subassembly. Adopting Oil-resistant plastic substitute thin brass board to make returned oil floater. Suggesting change a new floater as found any abnormal transformation of floater. Inspect returned oil valve. There are two situations exhausting pipe leakage caused by the returned oil valve. One situation is that returned oil valve is cemented due to extensive oil. In this case it is suggested to clean valve and reassemble it. Another situation appears because the returned oil valve is stuck. Taking away burr or waste on leader and reassemble it reference to Diagram 2-13. 3.3 No delivery or inefficient discharge caused by vapor separator Examine filter. A blocked filter not only affects fuel the suction capacity, but also generates abnormal noise. It is suggested to clean and reassemble filter. Don’t use brush to clean metal net so as not to increase net hole and affect filter accuracy. Inspect check valve. If check valve is stuck fuel dispenser can’t discharge any oil. The method to solve the problem is to clean waste after disconnecting spring seat, spring and check valve, and reassemble it. Make sure that the movement of check valve is agile. Inspect the leakage between tank and fuel dispensers. The inspection is conducted with filter check. If no oil fuel dispenser or oil level go down slowly in low pressures chamber, there must leakage in bottom valve or pipeline. If there is still leakage occurred after solve above problem, carefully examine fuel dispenser fuel dispenser

hour siege that claimed remarkably few casualties (two dead prison guards), captured the prisoners alive. In response, furious Palestinians set fire to the British Council offices in Gaza, and several foreigners were kidnapped in Gaza and the West Bank, only to be released unharmed soon afterwards. The monitors were there as part of a deal struck in 2002, when Israel agreed to lift its siege of Yasser Arafat s compound in Ramallah, where the six men were hiding out, in return for their handover. Among them was Ahmad Saadat, a leader of the Popular Front for the Liberation of Palestine (PFLP), who was believed to have planned the assassination of Rehavam Zeevi, a right-wing Israeli cabinet minister. Israel agreed to let the men stay in a PA jail, so long as there was foreign supervision. But the supervisors had never been happy with the poor security provisions for the unarmed monitors and the lax conditions for the prisoners, who were, for instance, allowed to use mobile phones. Israel suspects that Mr Saadat used one to plan a suicide bombing from his cell. After Mr Saadat won a seat in the Palestinian parliament last January on the PFLP list, the organisation began calling on the Palestinian president, Mahmoud Abbas, to release him. Hamas, which won a majority in the legislature, said that it would let him go once it formed a government. That seems to have tipped the balance for the British and the Americans rather than wait for the prisoners to be set free, and risk having their monitors caught in an Israeli attack, they pulled out pre-emptively. Israel, they say, knew nothing about it before March 8th, though Israel s Haaretz newspaper reports that the Israeli plans had been laid weeks before. (The army refused to comment.) Opening the way to an Israeli siege would have been a sensitive matter at the b fuel dispenser est of times. But with foreign donors engaged in backroom debates about the extent to which they should cut funding for, and contact with, a Hamas-run PA, Palestinians inevitably w fuel dispenser onder fuel dispenser
