U403 Emergency shut-valve

U403 Series Emergency Shut-off Valve are installed on fuel supply lines beneath at grade level to minimize hazards associated with collision or fire at the dispenser. If the dispenser is pulled over or dislodged by collision, the top of the valve breaks off the flow of fuel. Single-poppet models shut off supply flow, while double-poppet models shut off supply as well as prevent release of fuel from the dispenser's internal piping. The base of the Emergency Valve is securely anchored to the concrete dispenser island through a stabilizer bar system within a U-Bolt Assembly. Valve inlet (bottom) connection are female pipe threads and outlet (top) connections are available with female threads, male threads, or a union fitting. Other options include suction system models with a normally closed secondary poppet which maintain prime, and models with external threads on inlet body which connect to secondary containment system.

    , exercise, motivation and socialist solidarity. Cassava and pork-fat Mr Martínez, their poster-boy, certainly got exercise. He was a labourer all his life, cutting sugar cane (on Mr Castro s father s ranch, among others) and helping build the Central Highway. He worked so fast with the guataca, a small hoe, that his friends called him “El Avión� the aeroplane. Like most Cubans, he had no car; he biked or walked barefoot, or waited for a fume-spilling bus with that patience and stoicism that calms down stress. Since food was rationed, he did not eat much except what he could grow. Apart from all that, his life was not exemplary. He smoked until the age of 108 or so, cigarettes being handed out cheap among his rations. He never married, but chased many women. His “fresh�diet was mostly starchy cassava and sweet fuel dispenser potatoes cooked in pork fat. Asked the secret of his youthfulness, he said he had never cheated a man or said bad things of other people. And he had a good socialist motivation to survive he wished, someday, to shake Fidel Castro s hand. Cuba s cradle-to-grave health care had in fact done little for him. He did not consult a doctor until he was around 115, and never went to hospital until the last few days of his life. Had he needed care earlier it would have been astonishingly good for a developing country, but standards are lower now than in the past. Money has been siphoned elsewhere, to “health tourism� ordinary patients must bring their own lightbulbs and bedsheets. Cuba s best levels of health care, like its centenarians, are put on display mostly to show the world what it can do. And what of that other elderly man fuel dispenser , bearded and now frail, recovering slowly from “intestinal bleeding� but still the longest-serving ruler in the world? Why, says his optimistic doctor, he may still survive to 125; for he is lucky enough to live in Cuba, the site of the Fountain of Youth. © 2006 . fuel dispenser
