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.

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.

the product vary largely and different performance and failure as well. The following just introduce some general methods to solve troubles. 3.1. Inefficient performance The bad separate capacity present as: large foam appears in oil indicator as refueling, accuracy is affected. Maintenance methods and procedure as followed. Firstly to check the nut and plug on strainer whether loose, whether leakage at joint face as stopping operation. If failure is still exists after solve the sealing problem of strainer cover, conduct next progress. Check whether pipeline leakage between tank and fuel dispensers. The check method is to disconnect the end cover of strainer, and to find whether exist oil in low pressure chamber; if no oil or oil level go down slowly, there is some leaking places in pipeline or bottom valve. Inspect exhausting valve seat. Open upper cover and inspect the small hole at exhausting valve seat whether stuck. If the hole is stuck or narrowed by waste, oil indicator would appear much foam due to air leaking into vapor separate chamber. T fuel dispenser he method to solve trouble is that dredge hole and clean groove, making enough area. Note that the area should don’t too large, large room easily causes leaking oil at exhausting pipe. Check vapor separate chamber. Under normal condition oil level in the chamber should keep a half capacity so that ensure air can’t reach into low pressure chamber. (Different products with various oil level). If there is no oil or low level in vapor separate chamber, the taper valve would not plug the hole of return oil valve seat, so fuel dispenser as air reaching into low pressure chamber via taper valve and returned oil valve. The solution is that inspecting the axis of returned valve and the hole of returned oil valve seat. Reassembling them after solve problems. 3.2. Exhaust pipe leakage When tank position is higher than that of fuel dispenser, exhausting pipe will leak oil. Plugging exhausting pipe could solve leakage phenomenon. If found leakage on tank the following procedure fuel dispenser

drissov Ambassador for Kazakhstan London The relevance of irrelevance SIR �You misunderstand the nature of the “irrelevance theory�of Franco Modigliani and Merton Miller (Economics focus, February 11th). Their point is not that a firm s financial structure should be irrelevant in practice; instead it is that capital structure would be irrelevant in a world of perfect markets, and thus the search for the optimal structure should focus on market imperfections. Indeed, Modigliani and Miller themselves relax the perfect markets assumption when examining the effect of taxes on capital structure. They certainly did not “set back for a generation the study by economists of corporate finance� In fact, Jean Tirole, whose book you were reviewing, actually praises the Modigliani and Miller result as a “detonator for the theory of corporate finance, a benchmark whose assumptions needed to be relaxed in order to investigate the determinants of financial structures� fuel dispenser David Goldreich Associate professor of finance Rotman School of Management University of Toronto Toronto Baggage claims SIR �If airlines are serious about wanting to save fuel by encouraging passengers to travel more lightly they should charge passengers on a per-kilo basis (“Light up� February 11th). I am routinely seated next to people whose body weight exceeds my own by much more than the permitted baggage allowance. fuel dispenser Gary Holton Fairbanks, Alaska SIR �So some airlines are going to penalise passengers who want to check their bags. Have they taken into account the injuries to customers resulting from the brutal battles for increasingly scarce space in overhead compartments that will undoubtedly follow?
