U404 Foot Valve

U404 Foot Valve

Materials:

Body: Brass

Valve: Brass

Seal : Buna-N / Viton

Features :

Valve closing speed:0.5S

Medium: Gasoline, diesel , and kerosene

Operating Temperature: -30~~+55degree

U404 Series Foot Valves are installed on the bottom of suction tubes in the fuel storage tank to maintain prime in suction system fuel lines.

Double-poppet models provide redundant protection for holding the prime, and are ideal for installations where the valve is not easily accessible.

U404 Series Foot Valves feature precision metal-to-metal sealing arrangements.U404 Series Foot Valves are recommended for use on suction lines where the pressure does not exceed 34 ft of head (approximately 15 psi).

U404 Series Foot Valves are pressured tested to ensure accuracy

Screen protects the valve from debris

100% Factory Tested.

This device often is installed on check valve, hose pipeline also release certain hydraulic pressure. Pipe Resonance Apart from hydraulic stock, other hydraulic components also cause a certain degree of noise in pipeline, such as vane pump, overflow valve, vapor separator, measurement transducer, solenoid valve and nozzle. Sometime pipe resonance will be generated if the inherent frequency of pipe equivalent to hydraulic pulse resulted from hydraulic components of fuel dispenser. At that time, the normal working state will be affected, which is harmful to staff’s health due to inte fuel dispenser nsive noise. In order to explain this problem, the inherent frequency of pipe is introduced here. Pipe inherent frequency is: ω0 = kπ/2 l2 ·EJgGd+Gj (2-14) In the above formula: ω0 ── inherent frequency of pipe l ── supporting point distance E ── elastic modulus of pipe material J ── inertial moment of pipe section g── acceleration of gravity Gd── weight of pipe per meter Gj──liquid weight in per meter of pipe K── modifying coefficient K= 1-pA+mv/2π2EJA/l2 (2-15) In above formula: A ──pipe section m ──liquid weight in per meter o fuel dispenser f pipe v ──velocity of flow of liquid in pipe Several relative parameters affect the inherent frequency of pipe in Formula 2-14. Therefore, most manufacturers pay much attention to these elements that fuel dispenser affect pipe inherent frequency and pulse frequency of hydraulic components in the design and manufacture of fuel dispenser, making the two frequencies as much different as possible so as to appear pipe resonance in fuel dispenser. 3. Hose used for fuel dispenser There are two kinds of hose used in fuel dispenser. one is made according to GB/T10543 Rubber Hose Used for Refueling and Discharge of Airplane, connected oil indicator with nozzle; the other kind of hose is used in fuel dispenser with vapor recovery device, not only connecting oil indicator with nozzle,

ek s meeting of employment ministers, but the French, Italians and Spaniards will persist. When Europe is losing market share to harder-working Asians and Americans, it seems mad to stop the few people who want to work long hours from doing so. There is a similar hostility to workers from the east. Earlier this year a Danish carpenter, noting that Polish carpenters can do the same job for a quarter of the price, said bluntly that was “not the kind of competition we want in Europe� Worse, the benefits of the single market seem surprisingly modest to many. And Mr Verheugen himsel fuel dispenser f has put the cost of complying with EU regulations at as much as �00 billion a year. No wonder a recent poll of British businessmen found a majority claiming to believe that the costs of regulation outweigh the benefits of the single market. It is fair to concede that there are doubts about all cost-benefit calculations applied to regulation. The EU is more than just a single market; there are many other benefits to membership. Regulation is bound to cost money—if it did not, it would not serve its presumed purpose. If EU red tape did not exist, much of it would be reinvented at national level. (Some national regulatory regimes m fuel dispenser ight be more onerous than EU ones, although others would surely be lighter.) It is also true that deregulatory zeal is still alive in parts of the commission. Still, it is plain that the benefits of th fuel dispenser e single market have been less than enthusiasts hoped, and the costs may have been bigger. And, to judge by the changing climate of opinion about the single market, few people are ready to do anything about this. © 2006 .  About sponsorship Financing universities Mendicant scholars Nov 9th 2006 From The Economist print edition An arcane dispute at Oxford brings the financial strains in higher education into sharp relief.
