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.

Materials:

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 ?

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.

    of four-piston measurement transducer The upper subassembly includes inlet and outlet of oil. The export axis stretches out of measurement transducer from the hole of upper cover unit. The middle of frame unit is a solid chamber, connecting with four cylinders mounted stainless st fuel dispenser eel bushing. There is an oblong passage on top of each cylinder, which is communicated with lower part of cylinder. These oblong passages also communicate with annular grooves related on top of frame. Four pistons mounted idler wheels are installed respectively into bushings related, connecting piston with connecting rod at same axes. Camshaft unit insert into the oblong groove in middle of connecting rod. Shaft is supported by installi fuel dispenser ng hole at lower frame and valve seat. D and U bearing are mounted in the two holes. Four end covers are installed at each end of frame, of which adjusting device being installed at one end cover to regulate the moving distance of piston concerned. Adjusting device regulates the discharge of measurement transducer so as to ensure the accuracy. Distributing valve and valve seat are installed at top of frame unit. 1-Seal gasket 2-Upper cover unit/O-ring 3-Drive fork/output shaft 4-Spring\O-ring\valve cover\seal\gasket 5-Frame\distributing valve\valve seat\connecting rod\cam\cam axis 6-Piston\clamp sheet\pin 7-End cover\adjusting bolt\gasket\regulating wheel Diagram 2-21: Exploded view of four-piston measurement transducer Working principle The pressured oil coming from vapor separator or submersible pump flows into distributing valve via measurement transducer and continuously flow into relevant cylinder via the oblong passage at top of frame so as to drive piston moving. Likewise, the piston impels opposite piston through connecting rod, pressured oil flows out the outlet of upper cover via the passages at top of cylinder and then the inboard window of distributing valve.

    ators worry that, should a hedge fund implode, it could damage the whole financial system. This fear is not unfounded regulators remember a close shave with Long Term Capital Management, a hedge fund stuffed with Nobel laureates, in 1998. Watchdogs are also concerned by the ch fuel dispenser anges in the mix of hedge-fund investors, even though they are still mostly the preserve of the super-rich. Public and private pension money has started to flow into hedge funds. The idea that some of the retirement savings of teachers and firemen are invested in unregulated funds makes some regulators uneasy, however sophisticated pension-fund managers may be. The court s decision was based on semantics. Under old rules, hedg fuel dispenser e-fund advisers were exempt from regulation if they had fewer than 15 “clients? The SEC had long defined these to be the institutions whose money a hedge fund administered, rather than their individual investors. But the new rule defined clients as investors. This, said the court, was arbitrary. It struck down the rule. The effect of this decision is unclear. Many hedge funds are likely to stay registered, to reassure institutional investors. And although the SEC may no longer examine individual hedge funds, even supporters of regulation admit that the commission lacked the manpower to police the industry effectively. The SEC s biggest loss, says John Coffee, of Columbia University s law school, is the “census information”—on assets, debt and the like—that might have improved its understanding of the hedge-fund industry. Christopher Cox, the head of the SEC, has said that the agency will “re-evaluate?its options. It does not have many. An appeal to the Supreme Court, says Mr Coffee, would probably fail. So would attempts to tinker with the rules in the hope of satisfying the court on a second visit. Any regulatory push, therefore, is likely to be left to Congress.
