U404 Foot Valve

U404

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.

    Exploded drawing of double flux solenoid valve From above diagrams, it is known that this kind of solenoid valve consists mainly of valve body, membrane, con fuel dispenser e-shaped spring, valve cover, pilot valve, control valve of small flux, reposition valve, winding of pilot valve and small flux valve winding. The working principle of double flux solenoid valve can be leaned from Diagram 2-35. Pilot valve, small flux valve and main valve controlled by membrane are closed after power cut, no oil pass solen fuel dispenser oid valve. When both two windings are open, pilot valve and small flux valve switch on, pressured oil pushing down membrane. Part of oil in A chamber flow toward outlet of solenoid valve via pilot valve and small flux valve, main valve is switched on after overcoming spring, at this state, solenoid valve is in large flux. When winding of pilot valve is cut power, pilot valve is closed, membrane go upward so as to close main valve due to oil pressure increase in A chamber. Solenoid valve is in small flux state. If the power of winding of small flux valve is cut off, small flux valve is closed, no flux in solenoid valve. It is learned from above introduction that the large and small flux of solenoid valve are controlled by pilot valve and small flux valve. This is why it called double flux solenoid valve. As filing motor, pilot valve, small flux valve and main valve are switched on, fuel dispenser work in large flux state. When filling volume nearly reach presetting value, winding power of pilot val fuel dispenser ve is cut off, main valve is closed. However, small flux valve is still working. When filling volume reach preset-value, the winding power of small flux valve is cut off, solenoid valve is closed. Filling operation is end. Troubleshooting In filing operation some troubles maybe correlate to solenoid valve, some maybe to other hydraulic components. Small flux or no delivery in fuel dispenser, for example, it is possible caused by solenoid valve or other components. Therefore, it is need to give concrete analysis and diagno

    served, the hostess would ask “Are you a friend of the planter?�The expected answer was no; in which case no sugar would be offered. In 1817 Thomas Lov fuel dispenser e Peacock—a friend and neighbour of Shelley s in those days—wrote a tea-taking scene in his comic novel “Melincourt� The host, one Sylvan Forester, was based on Shelley. Forester was the organiser of the local Anti-Saccharine Society, never suffering “an atom of West Indian produce to pass my threshold� including the sugar concealed in fuel dispenser currant-jelly. When a guest, helping himself to tea, mildly observed that the sugar was missing, he drew down a rant that ended “How can the consumer of sugar pretend to throw on the grower of it the exclusive burden of their participated criminality?...the use of sugar is economically superfluous, physically pernicious, morally atrocious, and politically abominable.� The guest, shattered, “poured some cream into his unsweetened tea, drank it, and said nothing� He could have found arguments against, of course. Abstainers were told that their virtuousness was hurting commerce and depriving the country of revenue. By cutting the planters profits, they might also be worsening the condition of the very slaves they assumed they were helping. But most of all, they were hypocrites. If they were truly serious about boycotting slave produce, they would also eschew the coal in their fires and the shirts on their backs, both produced under dreadful conditions in Britain itself. Shelley, though h fuel dispenser e read accounts of the northern cotton mills, and was horrified by them, boycotted neither the coal nor the shirts. Like everyone else s, his consumer rage was selective. And then there was his sweet tooth. His friend Thomas Jefferson Hogg caught him one day making a peculiar dish called panada. He tore off “a surprising quantity�of bread, piled it in a bowl and poured on boiling water. Then he strewed it with nutmeg, which made it look interestingly gory. “I lap up the blood of murdered
