U403 Emergency shut-valve


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.


Body: cast iron(Spray-paint)

Surface: electronic Nickel plated

Seal : Buna-N O-ring

Features :

Flow rate: 0- 120 L/M

Working pressure: 0.2Mpa

Valve closing speed: 0.5s

Lowest shut-off temperature: 75 â„?

Medium: water, gasoline, diesel, and kerosene

Operating Environment: -30 ~+55degree

Fire Protection- a fusible link trips the valve closed at 75 to shut off fuel

supply to the dispense.

Integral Test Port - a 3/8" Test Port allows the piping system to be air tested

without breaking any piping connection.

Low-Profile Tops- Female and Union-top double-poppet valves have a low-profile top to allow upgrading from single-poppet valves without changing existing piping.

100% Factory Tested.

    g proof of filling station including awning mostly adopt lightningproof belt based on lightning condition of building and construction. It would be more economical. Metal pipe and line that connected indoors possibly generate spark and ignite vapor in some intervals of them as being attacked by direct lightning and lightning induction, resulting in explosion or fire. Thereby, this item of regulations is necessary. According to testing the burring length exceeding 50m at outdoors or 100m indoors or at least two grounding points with no more than 20 in lead pipe will largely reduce high electric potential indoors. Article II Wiring system The power load degree in fil fuel dispenser ling station is Class III. Power supply adopts 380V/220V in station. Mini internal-combustion generator is adopted as power supply. Its exhaust pipe mo fuel dispenser unts exhausting fire-resistance device. Horizontal distance from exhaust pipe to each explosion area should comply with the stipulation: if exhaust outlet under 4.5m ground the distance no less than 5m; if high than 4.5m, the distance no less than 3m. Electric line in filling station should adopt cable and burry, using steel pipe as line through vehicle road. If there are many lines a cable tunnel is suggested to use, filling with sand, exclusive other pipes. Article III Earth wire and grounding system The steel tank used for storing Class A oil should mount static-proof grounding device. The lightning conductor similarly used for this function. The starting and end point of delivery pipeline in tunnel or at ground should set static-proof and lightning induction device, grounding resistance no more than 30Ω. The vehicle tank discharge area in filling station should set static-proof grounding device, resistance no more than 100Ω. The design of static—proof grounding in forecourt should comply with the relevant stipulation of current national standard The Design and construction of forecourt.

    g civil servants wages on time while cutting the fiscal deficit. But the law tore up the terms on which the companies had invested. They are enclosing protest letters with every cheque. Mr Morales has a historic opportunity to use Bolivia s gas to overcome the country s backwardness. But that depends on two ambitious deals. The first might be an agreement to supply Chile with gas in return for Bolivian access to the sea. Chile s president, Ricardo Lagos, attended Mr Morales s inauguration. Mr Morales will be on hand when Michelle Bachelet is sworn in next month as Mr Lagos s successor. Second, there is scope for a deal with the multinationals. Mr Morales has ma fuel dispenser de soothing noises, promising “nationalisation�without expropriation. He has invited the companies to become “partners�of YPFB, the revived state oil fuel dispenser firm. If that means surrendering both their gas and the right to set export prices, the firms will want compensation and or big tax breaks on future investment. The main hope for compromise is that rupture could be worse for both sides. The companies would be forced to write off their investments. The government could seek deals with state oil companies in Venezuela and elsewhere but would face lawsuits in international courts. Expanding Bolivia s pipelines to Argentina and Brazil, and developing the gas to fill them, would cost $5.3 billion. “With these taxes and regional prices, investment is not viable,�says Mr Tavares. The new head of YPFB says that Bolivia will raise export prices to Argentina and Brazil. Demand for gas in Brazil is rising sharply. The country risks an electricity shortage in 2009 unless it finds new sources of gas. The squeeze may be temporary new finds offshore could turn Brazil into a gas exporter after 2012. Brazil s flirtation with Mr Chávez s pipeline may be a way to pressure Bolivia. Chile is roaming for gas as well. Having all but given up on Bolivia, it has talked of importing from Peru. Unlike its competitors, Peru has courted in fuel dispenser
