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.

bolt is first step as measurement accuracy beyond scope. If it doesn’t work, consider other solutions. Some oil is easily f fuel dispenser ull of colloid due to not in accordance with national standard or exposing to air in long storage. Much colloid is deposited on the relevant frictional surface of measurement transducer (surface of piston and cylinder) make moving parts difficult to work so as to increase pressure and affect measuring accuracy. The inlet pressure of measurement transducer usually is little under small flow rate. However, piston resistance is increased due to extensive colloid, even easily appear the phenomenon of refueling without measurement related. In this case, fuel dispenser delivery more oil than flow measured. Oil full of colloid is also affected the normal operation of vehicle motor. The cardinal solution to this problem is to control the quality and storage time of oil. Carefully clean the colloid on relative frictional surface of measurement transducer as occur the problem, and especially pay much attention to the friction surface so as not to damage mechanical parts. 1-Outlet elb fuel dispenser ow 2-End cover 3-Piston 4-Frame 5-Connecting sheet 6-Lower connecting rod 7-Upper connecting rod 8-Cylinder bushing 9-Adjusting bolt 10-Cap nut 11-Regualting piston 12-Driving elbow 13-Brass bushing 14-O-ring 15-Output shaft 16-Nylon wheel Diagram 2-19: Structural drawing of another kind of metal piston measurement transducer Accuracy decline and leakage caused by mechanical failure. The extensive mechanical abrasion of relevant friction surface of measurement transducer is main reason of causing accuracy beyond limitation. These parts abrasion result in accuracy decline, such as connecting board, bushing, small brass bushing used as adjusting piston, regulative piston, nylon wheel, etc. The O-rings between connecting rod and piston and on driving elbow tend to expansion to affect accuracy. Generally, disassemble and inspect all components, problem will be solved by changing extensive abrasion or damaged parts. fuel dispenser

Now it surpasses theirs. The country s sound monetary policy leaves it well placed to join the euro as planned in 2010, according to the OECD s latest survey. But the improvement in the country s fiscal fortunes reflects luck more than judgment. Tax revenues were stronger than expected and spending was deferred, not cut. © 2006 .  About sponsorship Economy Jun 15th 2006 From The Economist print edition © 2006 .  About sponsorship Financial fuel dispenser markets Jun 15th 2006 From The Economist print edition © 2006 .  SEARCH RESEARCH TOOLS Choose a research tool...
